A little complicatesd; but, you should be able to figure this out for yourself: Read the MAN page for modulefile man modulefile The section you want is about module-info Specifically this: module-info mode [modetype] The if statement is similar to the way I used module-info shell You might put this new test inside the module-info shell test (or maybe outside, depending on what you want). You need to decide which module modes need an action - and what action you want for each. Obviously, for the "load" mode you want the puts statement.

This shows me that the module load must outputting a string to bash that is only setting the first line of the file to the variable FOO, then the subsequent file lines are getting dropped right to bash to evaluate. >>>> >>>> Does anyone have ideas on how I can set a multiline variable from the contents of a file? >>>> >>>> (Some keywords for future searchability in the archives: multiline, multi-line, newline) >>>> >>>> Byron >>> >>> >>> _______________________________________________ >>> Modules-interest mailing list >>> Mod...@li... >>> https://lists.sourceforge.net/lists/listinfo/modules-interest >>> >> >> -- >> -------------------------------------------------------- >> The views and opinions expressed above are strictly >> those of the author(s).
