Hi I have defined log file in script

log_file -a $ logfile

I'm running some unix commands in script and I dont want the unix comamnd or its output (e.g ls ,mkdir etc )getting dummped to $logfile ...Tried log_user 0/1 but it did not help.

Is there a way to tell what needs to be logged to $logfile.

thanks

use 1>x and 2>y to redirect stdout and stderr in your script.

if you do this
cmda 1>/dev/null
cmdb 1>logfile.txt
cmdc 1>/dev/null

logfile.txt will only get output from cmdb.

I found a really awesome bash script started to log everything that happened to your script, you can review it here:
