Top Forums Shell Programming and Scripting How do I define a particular dir in PATH variable and then unset that dir Post 302273720 by jim mcnamara on Monday 5th of January 2009 03:06:21 PM

if you define a value for PATH inside a script, the value is only changed as far as the process running the script is concerned. "Nobody" else is ever affected. I think this may be the simple answer to your question. Changes to a child environment variable are NOT reflected in the parent process' same environment variable.
