UNIX for Advanced & Expert Users

Dear gurus,

I was wondering if anybody can help.

Is it possible to distinguish whether a script was launched from a shell (interactively) or was called from another script?

I basically need to do the following: if the script was run from the command line, I want to enable logging of the script into a file. If the script is called via another script, I do not wish to have any specific logging at all; instead I would like all std output and errors to be logged by the calling script's log

Any help would be greatly appreciated.

What system? What shell?

For BASH, my ~/.bashrc has this code:

Code:

if [[ $- != *i* ]]; then
        # Shell is non-interactive.  Be done now
        return
fi

apologies. This is Solaris 10, korn shell

I have tried this on a test shell script that just output a line on a logfile.

I tried then executing the script by running it from the shell prompt and by running another script that calls it. In both cases, the variable returned the same thing
