usage=&quot;Usage: $0 [OPTION]... [-e] PATTERN [FILE]...
Look for instances of PATTERN in the input FILEs, using their
uncompressed contents if they are compressed.

OPTIONs are the same as for &#039;grep&#039;, except that the following &#039;grep&#039;
options are not supported: --dereference-recursive (-R), --directories (-d),
--exclude, --exclude-from, --exclude-dir, --include, --null (-Z),
--null-data (-z), and --recursive (-r).
