NAME¶

wcd - Wherever Change Directory

chdir for DOS and Unix

SYNOPSIS¶

    wcd [options] [directory]

DESCRIPTION¶

    wcd Desk

    *       matches any sequence of characters (zero or more)
    ?       matches any character
    [SET]   matches any character in the specified set,
    [!SET]  or [^SET] matches any character not in the specified set.

    wcd *top

    wcd *top*

    wcd [a-c]*

    wcd me/Desk

    wcd src*/*1?/a*2

    wcd -g

    wcd ..

    wcd d:games

OPTIONS¶

-a

Add current path to the default treedata file.

Use this option to quickly add the current path to the default treedata file. Re-scanning the complete disk can take a long time in some cases.

-aa

Add current and all parent paths to the default treedata file.

-A PATH

Scan directory tree from PATH and append to the default treedata file. Examples:

    wcd -A .
    wcd -A /home -A /etc
    wcd -A d: -A e: -A \\server\share
    

On Windows one can scan all shared directories of a Windows LAN server by typing something like: "wcd -A \\servername".

See also option -S and -s and -E.

-b

Ban current path.

Wcd places the current path in the ban file. This means that wcd ignores all matches of this directory and its sub directories.

The ban file can be edited with a text editor. Use of wildcards is supported and names are matched against the absolute path.

Banned paths are not excluded from scanning the disk. To do that use option -xf.

-c, --direct-cd

Direct CD mode. By default wcd works as follows:

    1. Try to find a match in the treedata file(s)
    2. If no match, try to open the directory you typed.
    

In direct CD mode wcd works in reversed order.

    1. Try to open the directory you typed.
    2. If not, try to find a match in the treedata file(s).
    

-d DRIVE

Set drive for stack and go file (DOS only).

The stack file and the go-script are by default stored on drive C: if environment variable HOME is not set. Use this option if drive C: is a read-only drive. This option must be used in front of the stack options -, + and =.

-e

Add current path to the extra treedata file.

Use this option to quickly add the current path to the extra treedata file.

-ee

Add current and all parent paths to extra treedata file.

-E PATH

Scan directory tree from PATH and append to Extra treedata file. See also options -A and -S.

-f FILE

Read treedata file FILE. Do not read the default treedata file.

+f FILE

Read treedata file FILE in addition to the default treedata file.

-g

Graphical interface (only in version with curses interface).

Wcd starts a textual curses based 'graphical' interface. The user can select a directory via a full-screen interactive directory tree browser. It has a vim(1) like navigation and search method.

If no search string is given wcd presents the whole tree which is in the default treedata file and the extra treedata files.

If a search string is given the match list is presented as a directory tree.

The default tree layout is similar to the tree layout of the original NCD on DOS. The difference in layout is that in NCD all directories of a same depth level were vertically aligned over the whole tree. This was possible in NCD, because the maximum width of a directory name in DOS was 12 (8.3) characters. On modern operating systems directory names can be very long, so also the differences in length can be large. Therefore folders with a same depth are not vertically aligned over the whole tree in wcd, but only in sub-branches. So there is some sideways movement when moving straight up and down from one sub-branch to another sub-branch.

The navigation behaviour in Wcd is exactly the same as in the original NCD. For instance if you push the Down key you go down to the next directory with the same depth level, jumping over branches. This enables fast navigation through the tree.

See options -Ta, -TC, and -Tc to change the navigation behaviour.

-gd

Dump the treedata files as a tree to stdout.

-G PATH

Write go-script in directory PATH. For instance on Unix, "wcd -G PATH" will write a go-script PATH/wcd.go.

-GN, --no-go-script

Do not create go-script. This option can be used in combination with the option -j if one does not want wcd to create a go-script.

-h, --help

Show help and exit.

-i, --ignore-case

Ignore case. Dos and Windows versions of wcd ignore case default. Unix/Cygwin versions regard case by default.

+i, --no-ignore-case

Regard case. See also option -i.

-I, --ignore-diacritics

Ignore diacritics for Latin-based scripts. Letters with diacritical marks match their base letter without diacritical mark. The following Latin encodings are supported: CP437, CP850, CP852, CP1250, CP1252, ISO-8859-1, ISO-8859-2, and Unicode Latin-1, Latin Extended-A, and Latin Extended-B. See also <http://en.wikipedia.org/wiki/Diacritic>

+I, --no-ignore-diacritics

Regard diacritics (default). See also option -I.

-j, --just-go

Just go mode.

In this mode wcd will not present a list when there is more than one directory that matches the given directory. Wcd will just change to the first option. When wcd is invoked again with the same arguments it will change to the next option, and so on.

Wcd will print the directory to go to to stdout. So a different installation method can be used. One could make the following function for a POSIX compatible shell:

    wcd ()
    {
        cd "$($HOME/bin/wcd.exe -j $@)"
    }
    

When you are using an old shell that doesn't support "$()" command substitution you have to use old style command substitution with back-quotes.

    wcd ()
    {
        cd "`$HOME/bin/wcd.exe -j $@`"
    }
    

On Windows systems, if one is running 4NT shell, one could make the following alias:

    alias wcd `cd %@execstr[wcdwin32.exe -z 0 -j %1]`
    

This method eliminates the need of the go-script, so one can use option -GN in combination with -j.

-k, --keep-paths

Keep paths.

Keep paths in the treedata file when wcd can't change to them. The default behaviour of wcd is that it tries to remove paths from the treedata when wcd can't change to them. With this option this behavior is turned off.

-K, --color

Use colors in graphical mode.

-l ALIAS

Name the current path with ALIAS. Wcd places the current path with alias ALIAS in the alias file. Aliases are case sensitive.

-ls

Show the name of the alias file, and list all the aliases.

-m DIR

Make directory and add to treedata file.

-L, --license

Print the distribution license.

-M DIR

Make directory and add to extra treedata file.

-n PATH

Read relative treedata file from PATH.

Do not read the default treedata file. The relative treedata file should already have been created using the wcd +S option. PATH may also point to a file directly.

An example. Suppose another system has been mounted to mount point "/mnt/network":

    wcd -n /mnt/network src
    

Wcd opens the relative treedata file in "/mnt/network/". The file contains the paths relative from that point.

+n PATH

Read relative treedata file in addition to the default treedata file. See option -n.

-N, --numbers

Use numbers instead of letters.

Wcd with a conio or curses based interface (see section Interfaces) presents a match list by default numbered with letters. When the -N option is used the match list is numbered with numbers. Regardless of the -N option one can type a letter or numbers to make a selection from the list of matches.

-o

Use stdin/stdout interface.

When for some kind of reason the conio or curses interface of wcd does not work one can fall back to the stdin/stdout interface of wcd by using the -o option.

-od, --to-stdout

Dump all matches to stdout.

-q, --quiet

Quieter operation. Printing of the final match is suppressed.

-r DIR

Remove directory and remove from the treedata file.

If the directory is empty, wcd will remove it, and try to remove it from the treedata file.

-rmtree DIR

Recursively remove directory and remove from the treedata file.

Wcd will remove the directory and all its sub directories and files, and remove the directories from the treedata file.

-s

(re)Scan disk from $HOME directory. If HOME is not defined the disk is scanned from root directory /.

The existing default treedata file is overwritten.

The default scan directory can be overruled with environment variable "WCDSCAN". See section ENVIRONMENT VARIABLES.

-S PATH

Scan directory tree from PATH and overwrite the default treedata file. See also options -A, -s and -E. E.g. with option -A you can create a default treedata file of your choice. Examples:

Unix:

    wcd -S /
    wcd -S /home -A /etc -A /usr
    

DOS/Windows:

    wcd -S c:/
    wcd -S c: -A d: -A \\server\share
    

With the Windows versions one can scan all shared directories of a Windows LAN server by typing something like: "wcd -S \\servername".

+S PATH

Scan disk from PATH and place relative paths in a relative treedata file. This file is used by the -n and +n options of wcd. E.g. "wcd -n PATH src".

-t

Do not strip tmp mount dir "/tmp_mnt" (Unix only)

Wcd strips by default "/tmp_mnt/" from the match. Directory "/tmp_mnt" is used by the auto-mounter. This behaviour can be turned off with the -t option.

-T, --ascii-tree

Draw tree with ASCII characters. Use this option if line drawing characters are not displayed properly in your terminal.

-Ta, --alt-tree-nav

Alternative way of navigation in the graphical tree.

In the default NCD style tree layout the -Ta option disables jumping to unrelated directories.

In compact tree mode the alternative mode makes navigation similar to navigation in GUI file managers such as Windows Explorer or Linux KDE Konqueror. Pressing Up and Down moves the selected folder one line up or down. Pressing Left first folds the sub-folders and the next move left moves really left.

You can switch on-the-fly between default and alternative navigation by pressing <Shift-A>.

When alternative navigation mode is on, you will see an "A" in the lower right corner.

-TC, --center-tree

Centered view in the graphical tree. The selected directory stays in the middle of the screen. The centered mode can also be switched on and off with key <t> in the graphical tree.

The standard non-centered behaviour, which minimises tree movement, is the same as in the original NCD.

-Tc, --compact-tree

By default the 'graphical' tree is drawn the same way as the original NCD on DOS did it. On DOS a directory path could only be 66 characters in total. With the deep directory structures of today the tree can become very wide. To overcome this wcd can draw the tree in a compact way, similar to most GUI file managers, with only one folder per line. Use option -Tc or switch on-the-fly with the <m> key.

-Td, --cjk-width

Legacy East-Asian CJK (Chinese, Japanese, and Korean) fonts have certain characters and line drawing symbols with a column width of 2, while the normal Unicode width for these characters is 1 column. For instance the Chinese CP936 raster font on Windows and the Simsun font. Use this option for a correct outlining of the graphical tree when a legacy CJK font is used.

When CJK mode is on, you will see a "C" in the lower right corner.

-u USER

Scan treedata file of another user based on USER, do not scan your own default treedata file. See also section ENVIRONMENT VARIABLES for WCDUSERSHOME.

On Unix/Cygwin the base directory for user home directories is assumed to be "/home". Wcd will look for "/home/USER/.treedata.wcd" and "/home/USER/.wcd/.treedata.wcd", in that order, and read the first one that exists and is readable. On DOS/Windows the base directory for user home directories is assumed to be "\\users", so wcd tries to read "\\users\USER\treedata.wcd" and "\\users\USER\.wcd\treedata.wcd".

+u USER

Read default treedata file of USER in addition to your own treedata file.

-v, --verbose

Display verbose messages. With this option wcd prints all filters, bans and excludes.

-V, --version

Print version information and exit.

-w, --wild-match-only

Wild matching only. Treat all matches as wild matches.

-x PATH

Exclude PATH from scanning.

When this option is used wcd will exclude PATH and all its subdirectories when wcd is scanning a disk. Wildcards are supported and matched against absolute paths. Option -x can be used multiple times.

    wcd -x <path1> -x <path2> -s
    

Option -x must be used in front of any scan option (-s, -S, +S, -A, -E).

On DOS/Windows systems one must specify the drive letter depending on if environment variable HOME or WCDHOME is set. If HOME or WCDHOME is set one needs to specify the drive letter. An example:

    wcd -x c:/temp -S c:
    

Otherwise do not specify drive letter.

    wcd -x /temp -s
    

-xf FILE

Exclude all paths listed in FILE from scanning.

When this option is used wcd will exclude all paths listed in FILE and all their subdirectories when wcd is scanning a disk. Wildcards are supported and they are matched against absolute paths; one path per line. Be aware that wcd will not ignore leading or trailing blanks on a line, because they are legal characters in a directory name. Option -xf can be used multiple times. When one wants to exclude all banned paths from scanning one can do the following (example for wcd on unix):

    wcd -xf ~/.ban.wcd -s
    

Wildcards are supported. For instance to exclude all your Subversion directories with administrative files add a line with "*/.svn".

Option -xf must be used in front of any scan option (-s, -S, +S, -A, -E).

-y, --assume-yes

Assume Yes on all queries.

Wcd will not prompt the user with yes/no questions, but assumes the user answers yes on all questions. This can be used in combination with option -rmtree. This option must be used in front of options that can lead to yes/no questions.

-z NUMBER

Set maximum stack size to NUMBER.

The default size of the stack is 10. Stack operation can be turned off by setting the size to 0. This option must be used in front of any other stack operations (-,+,=). Otherwise the size of the stack will be set back to the default 10.

A correct command is:

    wcd -z 50 -
    

The new stack size will be 50, wcd will go one directory back. A wrong command is:

    wcd - -z 50
    

Wcd goes one directory back, the stack gets the default size 10. The -z 50 is ignored.

Add this option as the first option to your wcd alias or function. E.g. for the a POSIX compatible shell this would be:

    wcd ()
    {
        wcd.exe -z 50 "$@"
        . ${WCDHOME:-${HOME}}/bin/wcd.go
    }
    

-[NUMBER]

Push dir NUMBER of times. Default is one.

Go back a directory. Command "wcd -" goes one directory back. To go more directories back add a number to it. E.g. command "wcd -3". The stack is cyclic.

+[NUMBER]

Pop dir NUMBER of times. Default is one.

Go forward a directory. Command "wcd +" goes one directory forward. To go more directories forward add a number to it. E.g. command "wcd +2". The stack is cyclic.

=

Show stack.

Use this option if you do not know anymore how many times to push or pop. The stack is printed and you can choose a number. The current place in the stack is marked with an asterisk "*".

INSTALLATION¶

The current working directory of a Unix shell can only be changed by the builtin cd(1) command. Therefore the program is always called by a function or an alias. The function or alias sources a shell script (go-script) which is generated by the wcd program. Wcd can only work after the function or alias is defined.

Another important influence on your installation is the definition of environment variables HOME and WCDHOME. See section ENVIRONMENT VARIABLES.

    wcd ()
    {
        PATH/wcd.exe "$@"
        . ${WCDHOME:-${HOME}}/bin/wcd.go
    }

    wcd ()
    {
        PATH/wcdbash.exe "$@"
        . ${WCDHOME:-${HOME:-"c:"}}/wcd.go
    }

    wcd ()
    {
        PATH/wcdos2bash.exe "$@"
        . ${WCDHOME:-${HOME:-"c:"}}/wcd.go
    }

    wcd ()
    {
        PATH/wcdwin32zsh.exe "$@"
        . ${WCDHOME:-${HOME}}/wcd.go
    }

    if ( ${?WCDHOME} ) then
        alias wcd "PATH/wcd.exe \!* ; source $WCDHOME/bin/wcd.go"
    else
        alias wcd "PATH/wcd.exe \!* ; source $HOME/bin/wcd.go"
    endif

    function wcd
    {
        PATH\wcdwin32psh.exe $args
        & $env:HOME\wcdgo.ps1
    }

LOCALIZATION¶

LANG

The primary language is selected with the environment variable LANG. The LANG variable consists out of several parts. The first part is in small letters the language code. The second one is optional and is the country code in capital letters, preceded with an underscore. There is also an optional third part: character encoding, preceded with a dot. A few examples for POSIX standard type shells:

    export LANG=nl               Dutch
    export LANG=nl_NL            Dutch, The Netherlands
    export LANG=nl_BE            Dutch, Belgium
    export LANG=es_ES            Spanish, Spain
    export LANG=es_MX            Spanish, Mexico
    export LANG=en_US.iso88591   English, USA, Latin-1 encoding
    

For a complete list of language and country codes see the gettext(1) manual: <http://www.gnu.org/software/gettext/manual/gettext.html#Language-Codes> On Unix systems you can use to command locale(1) to get locale specific information.

LANGUAGE

With the LANGUAGE environment variable you can specify a priority list of languages, separated by colons. Wcd gives preference to LANGUAGE over LANG. For instance, first Dutch and then German: "LANGUAGE=nl:de". You have to first enable localization, by setting LANG or LC_ALL to a value other than C, before you can use a language priority list through the LANGUAGE variable. See also the gettext(1) manual: <http://www.gnu.org/software/gettext/manual/gettext.html#The-LANGUAGE-variable>

If you select a language which is not available you will get the standard English messages.

WCDLOCALEDIR

With the environment variable WCDLOCALEDIR the LOCALEDIR used during compilation and installation of wcd can be overruled. LOCALEDIR is used by wcd with native language support to find the language files. The GNU default value is "/usr/local/share/locale". By typing "wcd -V" wcd will print the LOCALEDIR that is used.

If you have installed wcd in a different directory than the default directory you may need to set the environment variable WCDLOCALEDIR to point to the locale directory.

An example for Windows cmd:

    set WCDLOCALEDIR=c:/my_prefix/share/locale
    

An example for a POSIX shell:

    export WCDLOCALEDIR=$HOME/share/locale
    

LC_COLLATE

When there are multiple directory matches wcd presents a sorted list. The sorting depends on the locale settings. If the environment LANG has been set the matches are sorted like dictionaries or phone books are sorted in that language. For instance dots and dashes are ignored, or letters e with and without accent are equal, or upper and lower case is ignored.

The sorting gives preference to environment variable LC_COLLATE over LANG. If you make LC_COLLATE equal to "C" or "POSIX", locale sorting is turned off. For instance if you want Dutch language, but not Dutch sorting, you can do something like this:

    export LANG=nl_NL
    export LC_COLLATE=C
    

LC_CTYPE

With regard to character encoding Wcd will give preference to variable LC_CTYPE over LANG. For instance to set character encoding to UTF-8 the following environment setting can be done.

    export LC_CTYPE=en_US.UTF-8
    

LC_ALL

All locale environment variables that start with LC_ are overruled by the environment variable LC_ALL if it is defined. Wcd gives preference to LC_ALL over LC_COLLATE and LC_CTYPE.

    LC_CTYPE=en_GB.UTF-8 xterm -u8 -fn '-Misc-Fixed-Medium-R-SemiCondensed--13-120-75-75-C-60-ISO10646-1'

FILES¶

If the environment variable WCDHOME is set wcd will use WCDHOME instead of HOME. All "*.wcd" files are text files. They can be edited with a text editor. The Windows Command Prompt version of wcd behaves as the DOS version. The Cygwin version of wcd behaves as the Unix version.

wcd.exe

The program. In Unix shells the program is always called by a function or alias, because the current working directory of a Unix shell can only be changed by the builtin cd command. See also section INSTALLATION.

default treedata file

This is the default treedata file where wcd searches for matches. If it is not readable wcd will create a new one.

    DOS: \treedata.wcd or %HOME%\treedata.wcd
    Unix: $HOME/.treedata.wcd
    

extra treedata file

An optional extra treedata file. If it exists and is readable wcd will try to find matches in this file also.

    DOS: \extra.wcd or %HOME%\extra.wcd
    Unix: $HOME/.extra.wcd
    

ban file

In this optional file wcd places banned paths. See option -b. Wildcards are supported.

    DOS: \ban.wcd or %HOME%\ban.wcd
    Unix: $HOME/.ban.wcd
    

alias file

Optional file with wcd aliases. See option -l.

    DOS: \alias.wcd or %HOME%\alias.wcd
    Unix: $HOME/.alias.wcd
    

stack file

In this file wcd stores its stack. The drive letter can be changed with the -d option.

    DOS: c:\stack.wcd or %HOME%\stack.wcd
    Unix: $HOME/.stack.wcd
    

The name of the stack file can be changed with environment variable WCDSTACKFILE. See section ENVIRONMENT VARIABLES.

go-script

This is the shell script which wcd.exe creates each time. It is sourced via a function or an alias. The drive letter can be changed with the -d option. For history reasons it is placed by default in "$HOME/bin" on Unix systems. The directory of this file can be changed with the option -G.

    DOS bash: c:/wcd.go or $HOME/wcd.go
    Windows Command Prompt: c:\wcdgo.bat or %HOME%\wcdgo.bat
    Windows PowerShell: $env:HOME\wcdgo.ps1
    WinZsh: $HOME/wcd.go
    Cygwin/MSYS: $HOME/bin/wcd.go
    OS/2 Command Prompt: c:\wcdgo.cmd or %HOME%\wcdgo.cmd
    OS/2 bash: c:/wcd.go or $HOME/wcd.go
    Unix: $HOME/bin/wcd.go
    

relative treedata file

Text file with relative paths from DIR. See options +S, -n and +n.

    DOS: PATH\rtdata.wcd
    Unix: PATH/.rtdata.wcd
    

ENVIRONMENT VARIABLES¶

HOME

Wcd uses by default environment variable HOME to determine where to store its files. See also section FILES. This can be overruled with environment variable WCDHOME.

HOME also defines where to start scanning the disk when option -s is used. This can be overruled with the environment variable WCDSCAN.

For the Unix, Cygwin, Windows PowerShell, WinZsh and MSYS version it is required that HOME or WCDHOME is set. For the other versions of wcd the use of these variables is optional.

If HOME is set on DOS/Windows, wcd will place all its files (treedata.wcd, extra.wcd, alias.wcd, ban.wcd, wcd.go) in directory HOME. The behaviour of wcd is then equal to the Unix version of wcd. Wcd will scan the disk default from HOME. Drives will not be automatically scanned by changing to them. You need to tell wcd explicitly. E.g.:

    wcd -S c: -A d: -A e:
    

Matching of directories is now global over all scanned drives.

WCDHOME

Environment variable WCDHOME can be used to change the location of wcd's files. If both HOME and WCDHOME are set, WCDHOME will be used instead of HOME.

In wcd versions prior to 5.1.5 WCDHOME also changed the default scan directory. This has changed. Since version 5.1.5 WCDHOME does not change the default scan directory. See option -s. From version 5.1.5, use environment WCDSCAN to overrule the default scan directory.

Example for DOS, Windows, OS/2 Command Prompt:

    set WCDHOME=C:\Users\erwin\wcd
    

An example for POSIX type shells:

    export WCDHOME="$HOME/.wcd"
    

An example for Csh type shells:

    setenv WCDHOME "$HOME/.wcd"
    

WCDSCAN

Use environment variable WCDSCAN to overrule the default scan directory HOME. Define a colon separated list (Unix) to define more than one directory. On DOS/Windows make the list semi-colon separated.

Examples for DOS, Windows, OS/2 Command Prompt:

    set WCDSCAN=C:\Users\erwin;D:\data
    set WCDSCAN=%HOMEDRIVE%%HOMEPATH%;\\projectdrive\projectX
    

An example for POSIX type shells:

    export WCDSCAN="$HOME:/projectdisk/projectX"
    

An example for Csh type shells:

    setenv WCDSCAN "$HOME:/projectdisk/projectX"
    

WCDFILTER

Specify filters with environment variable WCDFILTER. All directories that do not match the filter(s) are ignored. A list can be specified by separating filters by the shell path separator. Similar as specifying the PATH variable. The case sensitivity is mandated by the Operating system.

An example for DOS, Windows, OS/2 Command Prompt:

    set WCDFILTER=projects;doc
    

An example for POSIX type shells:

    export WCDFILTER="projects:doc"
    

An example for Csh type shells:

    setenv WCDFILTER "projects:doc"
    

WCDBAN

The paths specified with environment WCDBAN will be banned by wcd. See also option -b. Specify a list of paths separated by shell PATH separator.

WCDEXCLUDE

The paths specified with environment WCDEXCLUDE will be excluded by wcd. See also options -x and -xf. Specify a list of paths separated by shell PATH separator.

An example for DOS, Windows, OS/2 Command Prompt:

    set WCDEXCLUDE=*/windows;*/temp;*CVS
    

An example for POSIX type shells:

    export WCDEXCLUDE="/dev:/tmp:*CVS"
    

An example for Csh type shells:

    setenv WCDEXCLUDE "/dev:/tmp:*CVS"
    

WCDUSERSHOME

Set the base of user's home directories. On DOS/Windows the default value is "\\users". On Unix/Cygwin the default value is "/home". This variable is used to scan treedata files of other users. See also options -u and +u. In verbose mode wcd will print all filters, bans and excludes. See option -v.

WCDSTACKFILE

Wcd gives preference to WCDSTACKFILE over the default stack file name (see section FILES). With this variable each shell (or used terminal emulator) can have its private stack of used directories.

To use a unique time based YYYYMMDD-HHMMSS file for each opened interactive shell.

    export WCDSTACKFILE=$HOME/.wcd/stack.$(date +%Y%m%d-%H%M%S)
    

For a stack per xterm(1), use the xterm WINDOWID environment variable:

    export WCDSTACKFILE=$HOME/.wcd/stack.$WINDOWID
    

For GNU screen(1), to use stack per screen:

    export WCDSTACKFILE=$HOME/.wcd/stack.$WINDOW
    

TERMINFO

If the environment variable TERMINFO is defined, wcd with ncurses interface checks for a local terminal definition before checking in the standard place. This is useful if terminal definitions are not on a standard place. Often used standard places are "/usr/lib/terminfo" and "/usr/share/terminfo".

PDC_RESTORE_SCREEN

Wcd with PDCurses interface recognizes the environment variable PDC_RESTORE_SCREEN. If this environment variable is set, PDCurses will take a copy of the contents of the screen at the time that wcd is started; when wcd exits, the screen will be restored. An example for Windows Command Prompt:

    set PDC_RESTORE_SCREEN=1
    

Windows allows only a small buffer to be saved. So it is not always possible to restore everything. Some garbage data may be printed in the console after wcd exits if you have set a large buffer width.

SHELL

Printing of "#!$SHELL" on the first line of the go-script for POSIX type shell or C shell is needed for 8 bit characters. Some shells otherwise think that the go-script is a binary file and will not source it. In Cygwin Bash the variable SHELL must be set in environment using the "export" command, otherwise wcd can't read the variable.

BASH

Wcd for DOS bash uses $BASH instead of $SHELL, because $SHELL points to the DOS command shell. One may need to define $BASH with an "export" command, otherwise wcd can't read the variable.
