I'm trying to run a simple shell script in tcsh by creating a text file in emacs. It seems certain commands work and others don't. Note that the echo commands work, but the setenv and set commands do not. Each of these commands work when run individually from the shell prompt.

Here is the file, it's called "setup":

echo running
setenv CC g++
setenv LMALLOC
setenv LTHREAD -lpthread
echo finished

Here's what happens when I run it:
rtflynn> ./setup
running
./setup: line 2: setenv: command not found
./setup: line 3: setenv: command not found
./setup: line 4: setenv: command not found
finished
rtflynn>

I tried adding the line #! /bin/tcsh to the top of the file to ensure that the script was being run in the tcsh shell, but that didn't help. The "command not found" errors stopped showing up, but the setenv commands still did not work.

Any help on this issue would be greatly appreciated!

Are you positive that you're a) using tcsh
as your login-shell (cat /etc/passwd to check)
and b) when adding #!/bin/tcsh you're not supposed
to have a space after the ! and c) if you're running
the script rather than sourcing it you won't find
the environment variables your expecting even though
the script executed correctly

Thanks for your quick response!

a) I just confirmed that I was running tcsh by typing cat /etc/passwd
b) I got rid of the space and saw no change in the results
c) This may be my problem, but I'm not sure I understand what you mean by running vs. sourcing. Being a newbie, I don't know what the difference between these two ideas is. How do I source the script as opposed to run it?

source <script-name>

Got it! Thanks a lot!
