[SOLVED] avoid displaying errors while executing a script

vikas027 · 10-29-2007, 11:52 AM

Hi all,

I am running a script on bash shell, although it gives me the desired output, it displays some errors at the prompt like

this directory doesnt exists
unary operator
etc etc

Is there someway to avoid these errors ??
Its very annoying to have these errors while the script is executing.

Thanks

I would think that you would want to determine what lines/conditions are causing these errors and correct them (they are errors after all). If they are comming from lines that are executing something, but don't display anything that you need to see, you can just output everything from that command into /dev/null. But, without really knowing what the commands are, the entent of the script, and the desired output, I think that you'll be hard pressed to get a good answer. Kind of hard to work in the dark and all.

Proper quoting, checking variables and testing?

See: http://tldp.org/HOWTO/Bash-Prog-Intro-HOWTO-3.html for more info on redirecting stderr.

Hi all,

adding this line at top of the code helped

Quote:

exec 2>/dev/null

Thanks to all.
