Shell Programming and Scripting

I am trying to implement the below command in my shell script

su - $PROCESS -c `tar -tvf $file|tee -a $LOG/$file.log`

The idea is to get the tar output on the screen and at the same time it should put the output in the log file.

Problem is:
1) I donot get the output on the screen.
2) After the script exits it unsets stty erase parameter for my local shell.

Thank you is advance for your valuable inputs.

Try using " quotes, also you may as well do the tee part in the unprivileged shell, e.g.

Code:

su - $PROCESS -c "tar -tvf $file" | tee -a $LOG/$file.log

Thank for your reply, I tried wt you told me to.
I won't only to the list of tar file and not the output as below which it is currently putting in the log file. Kinldy advise.

Since you don't need to load the user's environment settings, etc. from .profile for such a simple command, you can omit the - to prevent that, i.e.:

Code:

su $PROCESS -c "tar -tvf $file" | tee -a $LOG/$file.log
