How to issue “module load” in a shell or Perl script (i.e., non-interactively)

Question

I can use the "module load xyz" command interactively, but when run from a script, it says it can't find the "module" command. Is there any way of loading modules in a script?

Answer 1

Start your bash script like this:

#!/bin/bash -l

Note that modules loaded after this with module load xyz will only be available from inside the script file.

Answer 2

Try

source /etc/profile

If that doesn't work, you most likely have a problem with aliases. You may need

shopt -s expand_aliases

in your script.

Answer 3

If by modules you mean Linux kernel modules, look into modprobe (or the more low-level insmod). There's usually no need to use whatever aliases (like module) that your Linux distro loaded into your shell.

(For example, I don't even have a module command on my distro/setup, so I can't try it to see what kind of modules you're referring to.)
