Shell Programming and Scripting

hmmm, what part are you not understanding?

quine has told you how to do that with command line, then when you posted it didn't work when you placed it in the script, I posted "not in the script but on the command line".
The only other alternative, is the 2nd option, "within the script", and yes, you'd then need to put on every line there is output..... so why not put it on the command line?? it sounds like want you're wanting to do.

Suggestion: try it! if it doesn't work, post exactly what you typed, and the resulting output.

Re-direct stderr of the entire shell script with an exec placed at the top right after the shebang line.

Code:

#!/usr/bin/ksh

exec 2> file.err

.

YES!
It was that i mean, I didn't know how to correctly write it.

Thank you shamrock
