How can a bash script be executed while loading a module in LMOD TCL?

edit

You can execute a bash script while loading a module in LMOD TCL by using the prereq function in LMOD. The prereq function allows you to specify dependencies that must be loaded before a module can be loaded, including running a bash script.

Here is an example of how to load a module and execute a bash script using the prereq function:

#%Module
prereq("/path/to/my/script.sh")

setenv MY_MODULE_VERSION "1.0"
setenv MY_MODULE_HOME "/path/to/my/module"
setenv PATH "$MY_MODULE_HOME/bin:$PATH"
setenv LD_LIBRARY_PATH "$MY_MODULE_HOME/lib:$LD_LIBRARY_PATH"

In this example, the prereq function is used to specify that the script at /path/to/my/script.sh must be run before the module can be loaded. The script could be used to set up environment variables or perform other tasks required by the module.

Once the script has been run and any dependencies have been loaded, the module's environment variables are set using the setenv function, as usual.
