Full Discussion: Dangerous rm -rf command
The Lounge War Stories Dangerous rm -rf command Post 302948317 by Riker1204 on Sunday 28th of June 2015 08:16:45 PM

Code:
var="/some/place"
rm -rf "${vra}/"*

Does the rm command throw an error when ${vra} does not exist or does it simply proceed with a null byte or something followed by /* erasing everything in its path.

As a beginner in Linux / Bash everything seems to bring up a question.
