Full Discussion: obsolete environment variables
Top Forums UNIX for Advanced & Expert Users obsolete environment variables Post 302073411 by System Shock on Friday 12th of May 2006 04:04:39 PM

There is no easy way to find out what script-binary-app uses which environment variable, but variables set by scripts are only set while the script is running and will unset once the script exits. So, if your script is a standalone script, i.e., not part of an application, chances are that $EXTRAPATH is useless to anything but the script that sets it. If it is part of an application, there is a chance that the application would read it and use it even after the script has exited, but I doubt it.
