Quick help with a unix shell script?

[chiwawa626]

I need to set a few environment variables before I run a certain program...how can I write a shell script to do this for me?

I tried to write a bash script that did something like "export MYDIR=/home/dir" but that did not set $MYDIR to what I wanted once the script was run.

please help?

My Unix is rusty but look at the setenv command.

export should work but if not, you can try setenv.

What are you running the script on?

you have to do something like $x = ENV{$MYVAR} .... I'll be right back and get the answer to you

 

[lancestorm]

the 'export MYVAL=blahblahblah' will set the env variable to that value. you do have to point the $MYVAL variable to the environment variable however, you can't just call the env variable name with a $ sign in front of it. You can do that by doing a $MYVAL = $ENV{'MYVAL'}

...when you do that command the $MYVAL value in your script will be set to the environment variable value that was exported to MYVAL

LET US KNOW if it works or not.

First we need to know which shell. Is this a bourne shell derivative or c shell?
