Hi,

I am running a utility that does not like a certain environment variable in my BASH shell. (No one in my team has it set). I need the utility and would like to unset the variable. It shows up like this:
BASH_FUNC_module()=() { eval `/usr/bin/modulecmd bash $*`
}
At the end of printenv output.
It looks like a function, however I do not know what it does.
How do I unset this? I am not even sure, how to parse this variable.
Which file holds environment variables and how are they sourced?
I have some experience in UNIX. In that environment I updated the .cshrc file and sourced it in my home directory.

This looks like a RedHatism involving the at utility. https://bugzilla.redhat.com/show_bug.cgi?id=1146958

Did you try unset BASH_FUNC_module ?
If you want to unset variable every time logon edit .bashrc file and at the end write:
unset BASH_FUNC_module

I am a bit confused that we seem to be talking about bash related variables but that you seem to be working in a cshell environement:

I know this post is old but it led me to one bug report which led to another which led to errata about the "at" command being fixed for this issue on RHEL6.

However, as noted in the latter bug report which is at:
https://bugzilla.redhat.com/show_bug.cgi?id=1147043

This is not just specific to the "at" command. Here we just ran across it when trying to relink Oracle on RHEL6.

The solution would be to unset this as noted in a prior post here but regular unset of a variable doesn't work because of the () at the end of BASH_FUNC(). The correct way to unset was in comment 47:
https://bugzilla.redhat.com/show_bug.cgi?id=1147043#c47

Doing that on RHEL6.8 worked to do the unset.

Oops - On RHEL6.8 it did unset the variable but gave error before doing it:
-bash: unset: `–f': not a valid identifier

Apparently you don't need the "-f" - just the rest of the line:
That will do it without the error but either way it does the unset.
