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.
