How do I change user in a script, and then carry on with the task at hand?
What I need to do is get the user to su to root, give the password of course, then carry on.
For instance:
su [and this then prompts for his password of course]
cd /home/fred/Desktop
[ now I would get him to enter a file name of a folder on his desktop and then...]
chown -R fred filename
What happens when I try this is that after changing accounts, the script stops.
Very basic question.........., sorry.

Interesting question! I played a bit, and found that one solution is to get the script, immediately after the "su", to invoke another script. Simple example:
[A] The initial script, file testchr.sh, permissions 777
#!/bin/bash su -c /home/ted/Misc/whatdo.sh
[B] The second script, file whatdo.sh, permissions 777
#!/bin/bash echo "Wow! I am" `whoami`
[C] In action:
ted@deb:~/Misc$ ./testchr.sh Password: Wow! I am root ted@deb:~/Misc$ whoami ted
Note that it returns to the original user after the script finishes.
Does this help? Ted.
