.SH NAME
module \- command interface to the Modules package
.SH SYNOPSIS
.sp
\fBmodule\fP [\fIswitches\fP] [\fIsub\-command\fP [\fIsub\-command\-args\fP]]
.SH DESCRIPTION
.sp
\fBmodule\fP is a user interface to the Modules package. The Modules
package provides for the dynamic modification of the user\(aqs environment
via \fImodulefiles\fP\&.
.sp
Each \fImodulefile\fP contains the information needed to configure the
shell for an application. Once the Modules package is initialized, the
environment can be modified on a per\-module basis using the \fBmodule\fP
command which interprets \fImodulefiles\fP\&. Typically \fImodulefiles\fP instruct
the \fBmodule\fP command to alter or set shell environment variables such
as \fBPATH\fP, \fBMANPATH\fP, etc. \fIModulefiles\fP may be shared by many
users on a system and users may have their own set to supplement or replace
the shared \fImodulefiles\fP\&.
.sp
The \fImodulefiles\fP are added to and removed from the current environment
by the user. The environment changes contained in a \fImodulefile\fP can be
summarized through the \fBmodule\fP command as well. If no arguments are
given, a summary of the \fBmodule\fP usage and \fIsub\-commands\fP are shown.
.sp
The action for the \fBmodule\fP command to take is described by the
\fIsub\-command\fP and its associated arguments.
.SS Package Initialization
.sp
The Modules package and the \fBmodule\fP command are initialized when a
shell\-specific initialization script is sourced into the shell. The script
executes the \fBautoinit\fP sub\-command of the \fBmodulecmd.tcl\fP
program located in \fB/usr/lib/x86_64-linux-gnu\fP for the corresponding shell. The output
of this execution is evaluated by shell which creates the \fBmodule\fP
command as either an alias or function and creates Modules environment
variables.
.sp
During this initialization process, if the Modules environment is found
undefined (when both \fI\%MODULEPATH\fP and \fI\%LOADEDMODULES\fP are
found either unset or empty), the \fBmodulespath\fP and \fBinitrc\fP
configuration files located in \fB/etc/environment-modules\fP are evaluated if present and
following this order. \fBmodulespath\fP file contains the list of
modulepaths to enable during initialization. In this file, the modulepaths are
separated by newline or colon characters. \fBinitrc\fP is a modulefile that
defines during initialization the modulepaths to enable, the modules to load
and the \fBmodule\fP configuration to apply.
.sp
During the initialization process, if the Modules environment is found defined
a \fI\%module refresh\fP is automatically applied to restore in the
current environment all non\-persistent components set by loaded modules.
.sp
The \fBmodule\fP alias or function executes the \fBmodulecmd.tcl\fP
program and has the shell evaluate the command\(aqs output. The first argument to
\fBmodulecmd.tcl\fP specifies the type of shell.
.sp
The initialization scripts are kept in \fB/usr/share/modules/init/<shell>\fP where
\fI<shell>\fP is the name of the sourcing shell. For example, a C Shell user
sources the \fB/usr/share/modules/init/csh\fP script. The sh, csh, tcsh, bash, ksh,
zsh, fish and cmd shells are supported by \fBmodulecmd.tcl\fP\&. In addition,
python, perl, ruby, tcl, cmake, r and lisp "shells" are supported which
writes the environment changes to stdout as python, perl, ruby, tcl, lisp,
r or cmake code.
.sp
Initialization may also be performed by directly calling the
\fBautoinit\fP sub\-command of the \fBmodulecmd.tcl\fP program.
.sp
A \fBml\fP alias or function may also be defined at initialization time
if enabled (see \fI\%MODULES_ML\fP section). \fBml\fP is a handy
frontend leveraging all \fBmodule\fP command capabilities with less
character typed. See ml(1) for detailed information.

.SS Modulecmd startup
.sp
Upon invocation \fBmodulecmd.tcl\fP sources a site\-specific configuration
script if it exists. Siteconfig script is a Tcl script located at
\fB/etc/environment-modules/siteconfig.tcl\fP\&. It enables to supersede any global variable or
procedure definition of \fBmodulecmd.tcl\fP\&. See \fI\%Site\-specific configuration\fP for detailed information.
.sp
Afterward, \fBmodulecmd.tcl\fP sources rc files which contain global,
user and \fImodulefile\fP specific setups. These files are interpreted as
\fImodulefiles\fP\&. See modulefile(4) for detailed information.
.sp
Upon invocation of \fBmodulecmd.tcl\fP module run\-command files are sourced
in the following order:
.INDENT 0.0
.IP 1. 3
Global RC file as specified by \fI\%MODULERCFILE\fP variable or
\fB/etc/environment-modules/rc\fP\&. If \fI\%MODULERCFILE\fP points to a directory, the
\fBmodulerc\fP file in this directory is used as global RC file.
.IP 2. 3
User specific module RC file \fB$HOME/.modulerc\fP
.IP 3. 3
All \fB\&.modulerc\fP and \fB\&.version\fP files found during modulefile
seeking.
.UNINDENT
.sp
These module run\-command files must begins like \fImodulefiles\fP with the
\fB#%Module\fP file signature, also called the Modules magic cookie. A version
number may be placed after this string. The version number reflects the
minimum version of \fBmodulecmd.tcl\fP required to interpret the run\-command
file. If a version number doesn\(aqt exist, then \fBmodulecmd.tcl\fP will
assume the run\-command file is compatible. Files without the magic cookie or
with a version number greater than the current version of
\fBmodulecmd.tcl\fP will not be interpreted and an error is reported. Such
error does not abort the whole \fBmodule\fP evaluation. If the
\fI\%mcookie_version_check\fP configuration is disabled the version number
set is not checked.
.sp

.SS Command line switches
.sp
The \fBmodule\fP command accepts command line switches as its first
parameter. These may be used to control output format of all information
displayed and the \fBmodule\fP behavior in case of locating and
interpreting \fImodulefiles\fP\&.

List all available \fImodulefiles\fP in the current \fI\%MODULEPATH\fP\&. All
directories in the \fI\%MODULEPATH\fP are recursively searched for files
containing the Modules magic cookie. If a \fIpattern\fP argument is given, then
each directory in the \fI\%MODULEPATH\fP is searched for \fImodulefiles\fP
whose pathname, symbolic version\-name or alias match \fIpattern\fP in a case
insensitive manner by default. \fIpattern\fP may contain wildcard characters.
Multiple versions of an application can be supported by creating a
subdirectory for the application containing \fImodulefiles\fP for each version.
.sp
Symbolic version\-names and aliases found in the search are displayed in the
result of this sub\-command. Symbolic version\-names are displayed next to
the \fImodulefile\fP they are assigned to within parenthesis. Aliases are listed
in the \fI\%MODULEPATH\fP section where they have been defined. To
distinguish aliases from \fImodulefiles\fP a \fB@\fP symbol is added within
parenthesis next to their name. Aliases defined through a global or user
specific module RC file are listed under the \fBglobal/user modulerc\fP
section.
.sp
When colored output is enabled and a specific graphical rendition is defined
for module \fIdefault\fP version, the \fBdefault\fP symbol is omitted and instead
the defined graphical rendition is applied to the relative modulefile. When
colored output is enabled and a specific graphical rendition is defined for
module alias, the \fB@\fP symbol is omitted. The defined graphical rendition
applies to the module alias name. See \fI\%MODULES_COLOR\fP and
\fI\%MODULES_COLORS\fP sections for details on colored output.
.sp
Module tags applying to the available \fImodulefiles\fP returned by the
\fI\%avail\fP sub\-command are reported along the module name they are
associated to (see \fI\%Module tags\fP section).
.sp
A \fIKey\fP section is added at the end of the output in case some elements are
reported in parentheses or chevrons along module name or if some graphical
rendition is made over some output elements. This \fIKey\fP section gives hints
on the meaning of such elements.
.sp
The parameter \fIpattern\fP may also refer to a symbolic modulefile name or a
modulefile alias. It may also leverage a specific syntax to finely select
module version (see \fI\%Advanced module version specifiers\fP section below).

.B config [\-\-dump\-state|name [value]|\-\-reset name]
Gets or sets \fBmodulecmd.tcl\fP options. Reports the currently set value
of passed option \fIname\fP or all existing options if no \fIname\fP passed. If a
\fIname\fP and a \fIvalue\fP are provided, the value of option \fIname\fP is set to
\fIvalue\fP\&. If command\-line switch \fB\-\-reset\fP is passed in addition to a
\fIname\fP, overridden value for option \fIname\fP is cleared.
.sp
When a reported option value differs from default value a mention is added
to indicate whether the overridden value is coming from a command\-line switch
(\fBcmd\-line\fP) or from an environment variable (\fBenv\-var\fP). When a reported
option value is locked and cannot be altered a (\fBlocked\fP) mention is added.
.sp
If no value is currently set for an option \fIname\fP, the mention \fB<undef>\fP is
reported.

restoring. It means that currently loaded modules are unloaded to get
the same \fI\%LOADEDMODULES\fP root than collection and currently used
module paths are unused to get the same \fI\%MODULEPATH\fP root. Then
missing module paths are used and missing modulefiles are loaded.

statements. Thus the effect a \fImodulefile\fP will have on the environment
may change depending upon the current state of the environment.
.sp
Environment variables are unset when unloading a \fImodulefile\fP\&. Thus, it is
possible to \fI\%load\fP a \fImodulefile\fP and then \fI\%unload\fP it without
having the environment variables return to their prior state.
.SS Advanced module version specifiers
.sp
When the advanced module version specifiers mechanism is enabled (see
\fI\%MODULES_ADVANCED_VERSION_SPEC\fP), the specification of modulefile
passed on Modules sub\-commands changes. After the module name a version
constraint and variants may be added.
.SS Version specifiers
.sp
After the module name a version constraint prefixed by the \fB@\fP character may
be added. It could be directly appended to the module name or separated from
it with a space character.
.sp
Constraints can be expressed to refine the selection of module version to:
.INDENT 0.0
.IP \(bu 2
a single version with the \fB@version\fP syntax, for instance \fBfoo@1.2.3\fP
syntax will select module \fBfoo/1.2.3\fP
.IP \(bu 2
a list of versions with the \fB@version1,version2,...\fP syntax, for instance
\fBfoo@1.2.3,1.10\fP will match modules \fBfoo/1.2.3\fP and \fBfoo/1.10\fP
.IP \(bu 2
a range of versions with the \fB@version1:\fP, \fB@:version2\fP and
\fB@version1:version2\fP syntaxes, for instance \fBfoo@1.2:\fP will select all
versions of module \fBfoo\fP greater than or equal to \fB1.2\fP, \fBfoo@:1.3\fP
will select all versions less than or equal to \fB1.3\fP and \fBfoo@1.2:1.3\fP
matches all versions between \fB1.2\fP and \fB1.3\fP including \fB1.2\fP and
\fB1.3\fP versions
.UNINDENT
.sp
Advanced specification of single version or list of versions may benefit from
the activation of the extended default mechanism (see
\fI\%MODULES_EXTENDED_DEFAULT\fP) to use an abbreviated notation like \fB@1\fP
to refer to more precise version numbers like \fB1.2.3\fP\&. Range of versions on
its side natively handles abbreviated versions.
.sp
In order to be specified in a range of versions or compared to a range of
versions, the version major element should corresponds to a number. For
instance \fB10a\fP, \fB1.2.3\fP, \fB1.foo\fP are versions valid for range
comparison whereas \fBdefault\fP or \fBfoo.2\fP versions are invalid for range
comparison.
.sp
Range of versions can be specified in version list, for instance
\fBfoo@:1.2,1.4:1.6,1.8:\fP\&. Such specification helps to exclude specific
versions, like versions \fB1.3\fP and \fB1.7\fP in previous example.
.sp
If the implicit default mechanism is also enabled (see
\fI\%MODULES_IMPLICIT_DEFAULT\fP), a \fBdefault\fP and \fBlatest\fP symbolic
versions are automatically defined for each module name (also at each
directory level for deep \fImodulefiles\fP). These automatic version symbols are
defined unless a symbolic version, alias, or regular module version already
exists for these \fBdefault\fP or \fBlatest\fP version names. Using the
\fBmod@latest\fP (or \fBmod/latest\fP) syntax ensures highest available version
will be selected.
.sp
The symbolic version \fBloaded\fP may be used over loaded module name to
designate the loaded version of the module with associated selected variants.
This version symbol should be specified using the \fB@\fP prefix notation (e.g.,
\fBfoo@loaded\fP). An error is returned if no version of designated module is
currently loaded.
.SS Variants
.sp
After the module name, variants can be specified. \fI\%Module variants\fP are
alternative evaluation of the same \fImodulefile\fP\&. A variant is specified by
associating a value to its name. This specification is then transmitted to the
evaluating \fImodulefile\fP which instantiates the variant in the
\fBModuleVariant\fP array variable when reaching the \fBvariant\fP
modulefile command declaring this variant.
.sp
Variant can be specified with the \fBname=value\fP syntax where \fIname\fP is the
declared variant name and \fIvalue\fP, the value this variant is set to when
evaluating the \fImodulefile\fP\&.
.sp
Boolean variants can be specified with the \fB+name\fP syntax to set this
variant on and with the \fB\-name\fP or \fB~name\fP syntaxes to set this variant
off. The \fB\-name\fP syntax is not supported on ml(1) command as the
minus sign already means to unload designated module. The \fB~name\fP and
\fB+name\fP syntaxes could also be defined appended to another specification
word (e.g., the module name, version or another variant specification),
whereas \fB\-name\fP syntax must be the start of a new specification word.
.sp
Boolean variants may also be specified with the \fBname=value\fP syntax. \fIvalue\fP
should be set to \fB1\fP, \fBtrue\fP, \fBt\fP, \fByes\fP, \fBy\fP or \fBon\fP to enable
the variant or it should be set to \fB0\fP, \fBfalse\fP, \fBf\fP, \fBno\fP, \fBn\fP or
\fBoff\fP to disable the variant.
.sp
Shortcuts may be used to abbreviate variant specification. The
\fI\%variant_shortcut\fP configuration option associates shortcut character
to variant name. With a shortcut defined, variant could be specified with the
\fB<shortcut>value\fP syntax. For instance if character \fB%\fP is set as a
shortcut for variant \fBfoo\fP, the \fB%value\fP syntax is equivalent to the
\fBfoo=value\fP syntax.
.sp
Specific characters used in variant specification syntax cannot be used as
part of the name of a module. These specific characters are \fB+\fP, \fB~\fP,
\fB=\fP and all characters set as variant shortcut. Exception is made for \fB+\fP
character which could be set one or several consecutive times at the end of
module name (e.g., \fIname+\fP or \fIname++\fP).
.SS Module tags
.sp
Module tags are piece of information that can be associated to individual
modulefiles. Tags could be purely informational or may lead to specific
behaviors.
.sp
Module tags may be inherited from the module state set by a modulefile command
or consequence of a module action. The inherited tags are:
.INDENT 0.0
.IP \(bu 2
\fBauto\-loaded\fP: module has been automatically loaded by another module
.IP \(bu 2
\fBforbidden\fP: module has been set \fIforbidden\fP through the use of the
\fBmodule\-forbid\fP command and thus this module cannot be loaded.
.IP \(bu 2
\fBhidden\fP: module has been set \fIhidden\fP through the use of the
\fBmodule\-hide\fP command and thus it is not reported by default among
the result of an \fI\%avail\fP sub\-command.
.IP \(bu 2
\fBhidden\-loaded\fP: module has been set \fIhidden once loaded\fP through the use
of the \fBmodule\-hide \-\-hidden\-loaded\fP command thus it is
not reported bu default among the result of a \fI\%list\fP sub\-command.
.IP \(bu 2
\fBloaded\fP: module is currently loaded
.IP \(bu 2
\fBnearly\-forbidden\fP: module will soon be \fIforbidden\fP, which has been set
through the use of the \fBmodule\-forbid\fP command. Thus this module
will soon not be able to load anymore.
.UNINDENT
.sp
Tags may also be associated to modules by using the \fBmodule\-tag\fP
modulefile command. Among tags that could be set this way, some have a special
meaning:
.INDENT 0.0
.IP \(bu 2
\fBkeep\-loaded\fP: auto\-loaded module cannot be automatically unloaded. This
tag is also set through the use of the \fBalways\-load\fP command.
.IP \(bu 2
\fBsticky\fP: module once loaded cannot be unloaded unless forced or reloaded
(see \fI\%Sticky modules\fP section)
.IP \(bu 2
\fBsuper\-sticky\fP: module once loaded cannot be unloaded unless reloaded,
module cannot be unloaded even if forced (see \fI\%Sticky modules\fP section)
.UNINDENT
.sp
The \fI\%\-\-tag\fP option helps to apply additional tags to modules. It is
available on \fI\%load\fP, \fI\%load\-any\fP, \fI\%switch\fP and
\fI\%try\-load\fP sub\-commands and on \fBalways\-load\fP,
\fBdepends\-on\fP, \fBmodule\fP, \fBprereq\fP, \fBprereq\-all\fP and
\fBprereq\-any\fP modulefile commands. In case the designated module is
already loaded, the additional tags are added to the list of tags already
applied to this module.
.sp
Module tags are reported along the module they are associated to on
\fI\%avail\fP and \fI\%list\fP sub\-command results and also when module\(aqs
loading, unloading, refreshing or tagging evaluation is mentioned. Tags could
be reported either:
.INDENT 0.0
.IP \(bu 2
along the module name, all tags set within angle brackets, each tag
separated from the others with a colon character (e.g.,
\fBfoo/1.2 <tag1:tag2>\fP).
.IP \(bu 2
graphically rendered over the module name for each tag associated to a
Select Graphic Rendition (SGR) code in the color palette (see
\fI\%MODULES_COLORS\fP)
.UNINDENT
.sp
When an abbreviated string is associated to a tag name (see
\fI\%MODULES_TAG_ABBREV\fP), this abbreviation is used to report tag along
the module name or the tag is graphically rendered over the module name if a
SGR code is associated with tag abbreviation in the color palette. With an
abbreviation set, the SGR code associated to the tag full name is ignored thus
an SGR code should be associated to the abbreviation to get a graphical
rendering of tag. If the abbreviation associated to a tag corresponds to the
empty string, tag is not reported.
.sp
Graphical rendering is made over the tag name or abbreviation instead of over
the module name for each tag name or abbreviation set in the
\fI\%MODULES_TAG_COLOR_NAME\fP environment variable.
.sp
When several tags have to be rendered graphically over the same module name,
each tag is rendered over a sub\-part of the module name. In case more tags
need to be rendered than the total number of characters in the module name,
the remaining tags are graphically rendered over the tag name instead of over
the module name.
.sp
When the JSON output mode is enabled (with \fI\%\-\-json\fP), tags are
reported by their name under the \fBtags\fP attribute. Tag abbreviation and
color rendering do not apply on JSON output.
.sp
Module tags cannot be used in search query to designate a modulefile.
.SS Sticky modules
.sp
Modules are said \fIsticky\fP when they cannot be unloaded (they stick to the
loaded environment). Two kind of stickiness can be distinguished:
.INDENT 0.0
.IP \(bu 2
\fBsticky\fP module: cannot be unloaded unless if the unload is forced or if
the module is reloaded after being unloaded or if restoring a collection.
.IP \(bu 2
\fBsuper\-sticky\fP module: cannot be unloaded unless if the module is reloaded
after being unloaded; super\-sticky modules cannot be unloaded even if the
unload is forced.
.UNINDENT
.sp
Modules are designated sticky by associating them the \fBsticky\fP or the
\fBsuper\-sticky\fP \fI\%module tag\fP with the \fBmodule\-tag\fP
modulefile command.
.sp
When stickiness is defined over the generic module name (and not over a
specific module version, a version list or a version range), sticky or
super\-sticky module can be swapped by another version of module. For instance
if the \fBsticky\fP tag is defined over \fIfoo\fP module, loaded module \fIfoo/1.2\fP
can be swapped by \fIfoo/2.0\fP\&. Such stickiness definition means one version of
module should stay loaded whatever version it is.
.sp
When restoring a \fI\%collection\fP or resetting to the initial
environment, sticky modules are unloaded to ensure \fI\%restore\fP or
\fI\%reset\fP sub\-commands fully set the environment in target collection or
initial state. Super\-sticky modules still cannot be unloaded with
\fI\%restore\fP and \fI\%reset\fP sub\-commands.
.SS Module variants
.sp
Module variants are alternative evaluation of the same \fImodulefile\fP\&. A variant
is specified by associating a value to its name when designating module.
Variant specification relies on the \fI\%Advanced module version specifiers\fP
mechanism.
.sp
Once specified, variant\(aqs value is transmitted to the evaluating \fImodulefile\fP
which instantiates the variant in the \fBModuleVariant\fP array variable
when reaching the \fBvariant\fP modulefile command declaring this variant.
For instance the \fBmodule load foo/1.2 bar=value1\fP command leads to the
evaluation of \fIfoo/1.2\fP modulefile with \fIbar=value1\fP variant specification.
When reaching the \fBvariant bar value1 value2 value3\fP command in modulefile
during its evaluation, the \fBModuleVariant(bar)\fP array element is set to
the \fBvalue1\fP string.
.sp
Once variants are instantiated, modulefile\(aqs code could check the variant
values to adapt the evaluation and define for instance different module
requirements or produce different environment variable setup.
.sp
Variants are interpreted in contexts where \fImodulefiles\fP are evaluated. Thus
the variants specified on module designation are ignored by the
\fI\%avail\fP, \fI\%whatis\fP, \fI\%is\-avail\fP, \fI\%path\fP or
\fI\%paths\fP sub\-commands.
.sp
When modulefile is evaluated a value should be specified for each variant this
modulefile declares. When reaching the \fBvariant\fP modulefile command
declaring a variant, an error is raised if no value is specified for this
variant and if no default value is declared. Specified variant value should
match a value from the declared accepted value list if such list is defined
otherwise an error is raised. Additionally if a variant is specified but does
not correspond to a variant declared in modulefile, an error is raised.
.sp
Module variants are reported along the module they are associated to on
\fI\%list\fP sub\-command results. Variants are reported within curly braces
next to module name, each variant definition separated from the others with a
colon character (e.g., \fBfoo/1.2{variant1=value:+variant2}\fP). Boolean
variants are reported with the \fB+name\fP or \fB\-name\fP syntaxes. When a
shortcut character is defined for a variant (see
\fI\%MODULES_VARIANT_SHORTCUT\fP) it is reported with the
\fB<shortcut>value\fP syntax. For instance if \fB%\fP character is defined as a
shortcut for \fIvariant1\fP: \fBfoo/1.2{%value:+variant2}\fP\&.
.sp
When the JSON output mode is enabled (with \fI\%\-\-json\fP), variants are
reported under the \fBvariants\fP JSON object as name/value pairs. Values of
Boolean variant are set as JSON Boolean. Other values are set as JSON strings.
Variant shortcut and color rendering do not apply on JSON output.
.SS Collections
.sp
Collections describe a sequence of \fI\%module use\fP then
\fI\%module load\fP commands that are interpreted by
\fBmodulecmd.tcl\fP to set the user environment as described by this
sequence.
.sp
Collections are generated by the \fI\%save\fP sub\-command that dumps the
current user environment state in terms of module paths and loaded modules. By
default collections are saved under the \fB$HOME/.module\fP directory.

.SS Site\-specific configuration
.sp
Siteconfig, the site\-specific configuration script, is a way to extend
\fBmodulecmd.tcl\fP\&. Siteconfig is a Tcl script. Its location is
\fB/etc/environment-modules/siteconfig.tcl\fP\&.
.sp
When \fBmodulecmd.tcl\fP is invoked it sources siteconfig script if it
exists. Any global variable or procedure of \fBmodulecmd.tcl\fP can be
redefined in siteconfig.
.sp
An additional siteconfig script may be specified through the
\fI\%extra_siteconfig\fP configuration option. The
\fI\%MODULES_SITECONFIG\fP environment variable is defined by
\fI\%config\fP sub\-command when setting \fI\%extra_siteconfig\fP\&. If it
exists the extra siteconfig is sourced by \fBmodulecmd.tcl\fP right after
main siteconfig script.
.SS Hooks
.sp
Siteconfig relies on the ability of the Tcl language to overwrite previously
defined variables and procedures. Sites may deploy their own Tcl code in
siteconfig to adapt \fBmodulecmd.tcl\fP to their specific needs. The
\fBtrace\fP Tcl command may especially be used to define hooks that are run when
entering or leaving a given procedure, or when a variable is read or written.
See \fBtrace(n)\fP man page for detailed information. The following
example setup a procedure that is executed before each modulefile evaluation:
.INDENT 0.0
.INDENT 3.5
.sp

   # code to run right before each modulefile evaluation
}
trace add execution execute\-modulefile enter beforeEval

.sp
Another possibility is to override the definition of an existing procedure by
first renaming its original version then creating a new procedure that will add
specific code and rely on the renamed original procedure for the rest. See
\fBrename(n)\fP man page for details. As an example, the following code
adds a new query option to the \fBmodule\-info\fP modulefile command:
.INDENT 0.0
.INDENT 3.5

.nf
.ft C
rename module\-info __module\-info

\fBCLICOLOR\fP equals to \fB0\fP\&. If \fBCLICOLOR\fP is set to another
value, it corresponds to the \fBauto\fP mode. The \fBalways\fP mode is set if
\fBCLICOLOR_FORCE\fP is set to a value different than \fB0\fP\&.
\fBNO_COLOR\fP variable prevails over \fBCLICOLOR\fP and

\fI\%Module tags\fP can also be colorized. The key to set in the color palette to
get a graphical rendering of a tag is the tag name or the tag abbreviation if
one is defined for tag. The SGR code applied to a tag name is ignored if an
abbreviation is set for this tag thus the SGR code should be defined for this
abbreviation to get a graphical rendering. Each basic tag has by default a

The configuration file evaluated by \fBmodulecmd.tcl\fP when it initializes
to enable the default modulepaths, load the default modules and set
\fBmodule\fP command configuration.
.sp
\fBinitrc\fP is a modulefile(4) so it is written as a Tcl script and
defines modulepaths to enable with \fBmodule use\fP, modules to
load with \fBmodule load\fP and configuration to apply with
\fI\%module config\fP\&. As any modulefile \fBinitrc\fP must begin
with the Modules magic cookie (i.e., \fB#%Module\fP file signature).
.sp
\fBinitrc\fP is optional. When this configuration file is present it is
evaluated after the \fBmodulespath\fP configuration file. See the
\fI\%Package Initialization\fP section for details.
