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.
