If you need to narrow down a list of folders in a directory to the set that you need to either archive or cleanup from a linux server, here's a quick command.
First, add the list of folders that you know you want to keep to a file named
file-list.txt. All other folders will be printed from this command.
$ ls -hal | grep ^d | grep -Fxvf file-list.txt
What the flags mean:
More than seven days old
Only search the current directory, not recursively
Interpret PATTERN as a list of fixed strings, separated by newlines, any of which is to be matched.
Select only those matches that exactly match the whole line.
Invert the sense of matching, to select non-matching lines.
-f FILE, --file=FILE
Obtain patterns from FILE, one per line. The empty file contains zero patterns, and therefore matches nothing.
If you want get a count to make sure the all folders listed in
file-list.txt exist in the current directory, here's another command.
$ ls -hal | grep ^d | grep -Fxf file-list.txt | wc -l
