PATH variable for a non-interactive session - SGI

Howdy,

I sent this out last week and checked this morning and didn't see the
article or any replies. So, I'm gonna send it again. I apologize if
you've read it before...

---

Me and a guy that I work with were working on a problem the other day
and the question came up as to where the PATH variable is set for a
non-interactive session. What I mean by a non-interactive session is
when you run a command on another machine via ssh using the syntax of

ssh loginname@hostname "command that you wanna run"

When I echo the $PATH in both cases, they are different.

Any ideas?

TIA,

Pete

Yup, depending on which shell you're using the environment can be set
based on several different files. Some of those files might not be used
when you're in a non-interactive session.
Since I use bash, I'll use that as example. It has basically two
"config" files *bashrc[1] and *profile[2]. The rc file is normally run
for non-interactive shells, while the profile does the setup for
interactive shells.
For csh style shells I believe the files are .(t)csh and .login - you'll
also have to check to see what the different files actually does. Do
they set the PATH variable only if you have and interactive terminal or
not?

Oh, and as a final note, ssh is usually compiled to provide some sort of
default PATH as well.

[1] /etc/profile, /etc/bash_profile, ~/.profile or ~/.bash_profile
(Whoever said it was supposed to be simple
[2] /etc/bash.bashrc or ~/.bashrc
