Added --exclude, cleanup args, fix -a count bug
Added --exclude to exclude patterns Cleaned up duplicated code in the args Fixed a bug when using --all because the count always returned "1" even when nothing matched entry=$($GREP "$query" "$tempdiff") count=$(echo "$entry" | wc -l) Example: $ touch testfile $ TEST123=$(grep 'test' testfile) $ echo "$TEST123" | wc -l 1
