Changing user and running commands inside of a script?

cory94bailly · 02-22-2011, 01:13 AM

My current script is as followed:

Code:

#!/bin/sh
su et
cd "media/ET"
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:.
exec ./ettv.x86 "$@"

That's probably completely wrong, I took the default ET script and tried adding my own additions.

The exact order I need to do things is:

Change users to "et"
CD to "/media/ET"
run ./ettv.x86

I want ET to be run as the user "et" and for some reason, I can't directly su/sudo to run the file without being in the user "et" and the "/media/ET" directory.

This may not be exactly "newbie" but I couldn't find any other forum and I'm hoping someone here can help.

Thanks

How about:

Code:

su -c 'cd /media/ET/ && LD_LIBRARY_PATH=$LD_LIBRARY_PATH:. ettv.x86' - et

When I tried that, I got this:

Quote:

cory@Cory-LAPTOP:~$ su -c 'cd /media/ET/ && LD_LIBRARY_PATH=$LD_LIBRARY_PATH:. ettv.x86' - et
Password:
No directory, logging in with HOME=/
-su: line 0: cd: /media/ET/: No such file or directory
cory@Cory-LAPTOP:~$

I have to be using the 'et' user in able to see/access the '/media/ET' directory. And I can't run the 'ettv.x86' without being in the directory.

It is a bit inconvenient but I guess I don't mind it :P

Also, is there a way to hardcode the password for 'et' into the script? I'm not worried about security issues at all, it's a laptop and it's for a user with access to only one directory.
