USAGE:
module use [-a|--append|-p|--prepend] [directory|group|release...]
Without arguments this sub-command displays information about
the module search path, used families and releases. You can
use this sub-command to get a list of available families and
releases.
With a directory as argument, this directory will either be
prepended or appended to the module search path. The default
is to prepend the directory.
With a group as argument, the modules in this group will
be made available.
With a release as argument, this modules with this release
will be made available.
SWITCHES:

USAGE:
module initadd modulefile...
Add modulefile(s) to the shell's initialization file in the
user's home directory. The startup files checked (in order)
are:
csh - .modules, .cshrc(.ext), .csh_variables, and
.login(.ext)
tcsh - .modules, .tcshrc, .cshrc(.ext), .csh_variables,
and .login(.ext)
(k)sh - .modules, .profile(.ext), and .kshenv(.ext)
bash - .modules, .bash_profile, .bash_login,
.profile(.ext) and .bashrc(.ext)
zsh - .modules, .zcshrc(.ext), .zshenv(.ext), and
.zlogin(.ext)
If a 'module load' line is found in any of these files, the
modulefile(s) is(are) appended to any existing list of
modulefiles. The 'module load' line must be located in at
least one of the files listed above for any of the 'init'
sub-commands to work properly. If the 'module load' line
line is found in multiple shell initialization files, all
of the lines are changed.
