grep for a list of values and list matching values NOT matching lines each time they match

goo some things you search for < file
If you want to know which values from a list are used within a file. Here's the bash function - called goo - for lack of a better name ;) function goo() { perl -e 'while (my $l = <STDIN>) { foreach (sort { length($b) <=> length($a) } @ARGV) { print "$_\n" x $l =~ s/$_//ig; } }' "$@" }
Sample Output
$ cat file 
grep for some stuff
this file
only list longest_match

$ goo foo match longest_match list bar < file
