I usually create a tgz file for my_files
with the command tar -czvf my_files.tgz my_files
, and extract them with tar -zxvf my_files.tgz
. Now I have a tar file created with the command tar -cvf my_files.tar my_files
. I'm wondering how I can turn the my_files.tar
into my_files.tgz
so that later I can extract it with the command tar -zxvf my_files.tgz
? Thanks.

A plain .tar
archive created with cf
(with or without v
) is uncompressed; to get a .tar.gz
or .tgz
archive, compress it:
gzip < my_files.tar > my_files.tgz
You might want to add -9
for better compression:
gzip -9 < my_files.tar > my_files.tgz
Both variants will leave both archives around; you can use
gzip -9 my_files.tar
instead, which will produce my_files.tar.gz
and delete my_files.tar
(if everything goes well). You can then rename my_files.tar.gz
to my_files.tgz
if you wish.
With many tar
implementations you can extract archives without specifying the z
option, and tar
will figure out what to do — so you can use the same command with compressed and uncompressed archives.

gunzip < my_files.tar.gz > my_files.tar
, orgunzip my_files.tar.gz
if you don’t want to keep the compressed archive. Oct 11, 2021 at 6:47
