hi all
can i redirect error to variable?

/dev/null
and use this variable later?

I think redirecting it to some file, will be a better idea. Like /tmp/my_script_err_$$

($$ will get the process id, so it will be unique)

Kamal,

You can, but the method Alex mentions might better. If you use a variable, take care with it if the error has spaces in it.

I do this in a bash script with redirecting it from the /dev/null with

command 2>&1 and vice versa

You can pipe the outpu to a file for example with

$cd DIR >> FILENAME 2>&1

the error output aswell will be put into the file.

Hope this helps for your purposes aswell,

Yes you can:

#!/bin/sh
ERROR=""

ls /doesnotexist >$ERROR 2>&1

echo $ERROR
