NAME¶

folder, folders - set/list current folder/message

SYNOPSIS¶

DESCRIPTION¶

Since the nmh environment is the shell, it is easy to lose track of the current folder from day to day. When folder is given the -print switch (the default), folder will list the current folder, the number of messages in it, the range of the messages (low-high), and the current message within the folder, and will flag extra files if they exist. An example of this summary is: If a +folder and/or msg are specified, they will become the current folder and/or message. By comparison, when a +folder argument is given, this corresponds to a “cd” operation in the shell; when no +folder argument is given, this corresponds roughly to a “pwd” operation in the shell. If the specified (or default) folder doesn't exist, the default action is to query the user as to whether the folder should be created; when standard input is not a tty, the answer to the query is assumed to be “yes”. Specifying -create will cause folder to create new folders without any query. (This is the easy way to create an empty folder for use later.) Specifying -nocreate will cause folder to exit without creating a non-existant folder.

Multiple Folders¶

Specifying -all will produce a summary line for each top-level folder in the user's nmh directory, sorted alphabetically. (If folder is invoked by a name ending with “s” (e.g. folders), -all is assumed). Specifying -recurse with -all will also produce a line for all sub-folders. These folders are all preceded by the read-only folders, which occur as “atr-cur-” entries in the user's nmh context. For example: The “+” after inbox indicates that it is the current folder. The “(others)” indicates that the folder ucom has files which aren't messages. These files may either be sub-folders, or files that don't belong under the nmh file naming scheme. The header is output if either a -all or a -header switch is specified. It is suppressed by -noheader. The folder and message totals are output if either a -all or a -total switch is specified. It is suppressed by -nototal. If -fast is given, only the folder name (or names in the case of -all) will be listed. (This is faster because the folders need not be read.) If a +folder is given along with the -all switch, folder will, in addition to setting the current folder, list the top-level subfolders for the current folder (with -norecurse) or list all sub-folders under the current folder recursively (with -recurse). If msg is supplied, together with +folder or without -all, it will become the current message of +folder (if it had been supplied) or the current folder. The -recurse switch lists each folder recursively, so use of this option effectively defeats the speed enhancement of the -fast option, since each folder must be searched for subfolders. Nevertheless, the combination of these options is useful.

Compacting a Folder¶

The -pack switch will compress the message names in the designated folders, removing holes in message numbering. The -verbose switch directs folder to tell the user the general actions that it is taking to compress the folder.

The Folder Stack¶

The -push switch directs folder to push the current folder onto the folder-stack, and make the +folder argument the current folder. If +folder is not given, the current folder and the top of the folder-stack are exchanged. This corresponds to the “pushd” operation in the shell. The -pop switch directs folder to discard the top of the folder-stack, after setting the current folder to that value. No +folder argument is allowed. This corresponds to the “popd” operation in the shell. The -push switch and the -pop switch are mutually exclusive: the last occurrence of either one overrides any previous occurrence of the other. Both of these switches also set -list by default. The -list switch directs folder to list the contents of the folder-stack. No +folder argument is allowed. After a successful -push or -pop, the -list action is taken, unless a -nolist switch follows them on the command line. This corresponds to the “dirs” operation in the shell. The -push, -pop, and -list switches turn off -print.

FILES¶

^$HOME/.mhprofile~^The user profile

PROFILE COMPONENTS¶

^Path:~^To determine the user's nmh directory
^Current-Folder:~^To find the default current folder
^Folder-Protect:~^To set mode when creating a new folder
^Folder-Stack:~^To determine the folder stack

SEE ALSO¶

refile(1), mhpath(1)

DEFAULTS¶

`+folder' defaults to the current folder
`msg' defaults to none
`-nofast'
`-noheader'
`-nototal'
`-nopack'
`-norecurse'
`-noverbose'
`-print' is the default if no -list, -push, or -pop is specified
`-list' is the default if -push, or -pop is specified

CONTEXT¶

If +folder and/or msg are given, they will become the current folder and/or message.

BUGS¶

There is no way to restore the default behavior (to ask the user whether to create a non-existant folder) after -create or -nocreate is given.
