switch user inside a script

permalink · #1 (**permalink**) 11-03-2005

Hi,
I wrote a unix script that will perform differnt tasks on bahalf of number of users. I use "sudo" to run the script. The problem is when I execute the command: su - user -c "xxx " > output_file, I get the system output header frm the su command. Is there a way to get rid of it instdead of doing further manipulation? Can I direct this to "null" device while the regular output will go the correct output file?

are you using sudo or su?

I am using "sudo" to run the script, and inside the script I use "su" several times. Each "su -user -c" to execute a certain command, and capture the log in a logfile. I would like to avoid having the system message (as a result of su) in the logfile.
