MAIL environment variable - what script sets this?

[DeSoya]

Question is in the title. I can't figure out where the MAIL environment variable is set. A 'grep -r MAIL' on /etc doesn't net anything remotely promising. It obviously gets set somewhere as it points to /var/mail/$USER. But changing that proves to be somewhat difficult for me as I can't find the right location.

And no I don't want to simply override the setting in my .bashrc or .bash_profile.

The only thing I have been able to find about this is that the tcsh ebuild installs a file named /etc/csh.cshrc which at the absolute end contains this code...

Code: Select all

...<snipp!>...

# Setup a default MAIL variable
if ( -f /var/mail/$USER ) then
    setenv MAIL /var/mail/$USER
    set mail = $MAIL
endif

You have run a recursive grep so you should have found this, but *shrug* it's the only thing I have found that sets a MAIL variable.

Good luck
