Command available at terminal prompt, but nowhere to be found

Question

This is puzzling. I can use the module command at the terminal prompt, but I can't find where the executable is located in the file system! I did the three following searchs:

1- which module returns "no module in ...",

2- searched module under the bin/ directories of the PATH variable ... nothing,

3- locate module | grep -e "/module$" ...nothing.

None of these searches gave me the location! Suggestions, please?

Answer 1

Is module perhaps set as an alias? You could try this:

type -a module

Answer 2

One more suggestion:

find / -name "module*"
