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

Try to redirect output or error device:

Code:

/path/to/command  > /dev/null

Or better:

Code:

/path/to/command >/dev/null 2>&1

It should work...

Code:

rmdir x

rmdir: x: No such file or directory

So I did

Code:

rmdir x > /dev/null 2>&1

No error, you must not put any space between 2>&1 treat it as one word

Hi all,

adding this line at top of the code helped

exec 2>/dev/null

Thanks to all.
