We have numerous directories that each contain 2 files, one of which is a hidden file. We want to remove all those directories and their contents that contain ONLY files that have a modification date older than 180 days. So, for example, if we have the following:
Dir1 Jan 1 2000 File1A Jan 1 2000 File1B Jan 1 2000 Dir2 Jan 1 2000 File2A Jan 1 2014 File2B Jan 1 2014 Dir3 Jan 1 2000 File3A Jan 1 2014 File3B Jan 1 2000
I need a Linux command that will remove only Dir1 and all of its contents including the hidden file. Dir2 and Dir 3 would remain untouched because each contain at least one file that is newer than 180 days ago.
I've played around with listing those directories that contain a newer file but I couldn't find an "inverse" command that would then remove all the "other" directories.
