gtouch : Creates a null file in gzip format.
Usage : gtouch <files>...
Version : Mon Jan 17 11:50:14 JST 2022
Edition : 1
If the specified files <files>... have content (are larger than zero
bytes), this command does nothing. If they are zero bytes or do not
exist, then a null file (20 bytes) in gzip format is created. When
this null file is unzipped, the result is zero bytes.
$ ls -l a.gz b.gz
