+Subject: [PATCH 1/3] 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
