Did someone think running "rm -rf /" is a good idea?
Quote from one of the people who commented on that article:
QUOTE:
You have this in a script: rm -rf "${DIRECTORY}"/
Now, you have a bug in the script and ${DIRECTORY} is not initialized. You then get rm
-rf / executed. One should always ensure that DIRECTORY is not empty before running this.
Or better, never end with /. If you have rm -rf "${DIRECTORY}", then only rm
-rf gets executed, causing rm to fail since no file/directory is provided.
END OF QUOTE
Yeah, that can happen, but I remember being taught that was an extremely
bad scripting practice back in 1998 when I took my first Linux class.
