For anyone curious, unless you are running a 'tar' binary from the stone ages, just skip the gunzip and cat invocations. Replace .gz with .xz or other well known file ending for different compression.
Examples:
tar -cf archive.tar.gz foo bar # Create archive.tar.gz from files foo and bar.
tar -tvf archive.tar.gz # List all files in archive.tar.gz verbosely.
tar -xf archive.tar.gz # Extract all files from archive.tar.gz
> tar -cf archive.tar.gz foo bar
This will create an uncompressed .tar with the wrong name. You need a z option to specify gzip.
Apparently this is now automatically determined by the file name, but I still habitually add the flag. 30 years of muscle memory is hard to break!
I tried it to check before making the comment. In Ubuntu 25.04 it does not automatically enable compression based on the filename. The automatic detection when extracting is based on file contents, not name.
