Gzip is an implementation of the Lempel-Ziv coding algorithm, it compresses files. The Mac OS X implementation of gzip varies a little from their *nix counterparts and it's a little tricky to use so I made this little guide to help myself. If I messed something up, please fork it and fix it!.
The most basic command will compress the file
filename.ext
and then replace it with filename.ext.gz
in the same directory.
If you don't want to lose your original file, then you need to pipe the output of
gzip -c
to a file.
Operating system support Unix-like operating systems usually include tools to support tar files, as well as utilities commonly used to compress them, such as gzip and bzip2. BSD-tar has been included in Microsoft Windows since Windows 10 April 2018 Update 14 15, and there are otherwise multiple third party tools available to read.

Gzip -c backup.disk.img.dd.gz: Create compressed disk image using gzip; You can verify your disk with file command. You can use ‘Disk Utility’ GUI tool to create and restore images. Sep 03, 2019 Gzip is one of the most popular compression algorithms that allow you to reduce the size of a file and keep the original file mode, ownership, and timestamp. Gzip also refers to the.gz file format and the gzip utility which is used to compress and decompress files. In this tutorial, we will show you how to use the gzip command. FTP uses commands, not scripts - so you cannot do a gzip command in an FTP transfer. Either before or after the file is handled by FTP, you can run a Unix System Services script in batch to zip (or unzip) the file using GZIP.
We can also compress from standard input, so we can compress the output of other commands.
OS X also comes with the
compress
and uncompress
commands. They make for a 'smarter' gzip, as it doesn't compress the file if it would grow after the compression process. The following command replaces filename.ext
with filename.ext.Z
in the same directory.
To restore a file to it's uncompressed natural state you can use gzip or other of the wrappers. The decompression mode of gzip is called with the
-d
flag. This mode will replace the file filename.ext.gz
with filename.ext
in the same directory. There's also a shortcut called gunzip
that will do the same.
We can also pipe the decompressed file to the standard output to save it to another file.
Another quick way of reading the content of a gzip to standard output is
zcat
, it's basically the same as calling gzip -cd
but you can call multiple files and have them concatenated the same way as the cat
command concats text files. The only drawback is that your files need to be suffixed with the .Z
suffix for it to work...
But fear not!
zcat
it's still useful, because it can decompress from standard output. So you can basically pipe your files to zcat to have them decompressed on the terminal window.
Application X Gzip
This is very useful if you need to check the content of a file really quick, and you can even save the output of zcat to a file, just as easy.

Gzip Utility For Os X Download
The
uncompress
wrapper works like gzip -cd
but it looks for files with the .Z extension to replace them in the current directory, so you only need to specify the file name you want to restore, but it's alright if you call it with the .Z extension, as the program will ignore it.
