Top Forums Shell Programming and Scripting [Solved] BASH - chaining TEST and COMMAND with && and II Post 302725411 by RudiC on Friday 2nd of November 2012 07:20:34 AM

Bakunin's explanation is correct and little to add for the cases covered. But the orig. request had a construct like A && B || C. In this case, C is the "fallback" branch in case A should fail:
Code:
$ true && echo "YES" || echo "NO"
YES
$ false  && echo "YES" || echo "NO"
NO

And this is what happens in the request: Variable B collects all packages to be installed and D all packages to be updated.
