The syntax of tar is fairly simple. To just compress a directory, you can use a command like this: tar czf linux- 5.10 -rc3.tar.gz linux / tar cjf linux- 5.10 -rc3.tar.bz2 linux / tar cJf linux- 5.10 -rc3.tar.xz linux / The first will use gzip, the second will use bzip2, and the third will use xz.

Tar compress xz

This will allow us to use xz options, like --extreme. tar cf - directory | xz -e > directory.tar.xz If you want to use low amount of memory you could try the option 4e for the xz which uses less memory, but it will be slower than the default. xz compression has been rising in popularity because it offers smaller file sizes than gzip and bzip2.You're still likely to see all three on a Linux system, but you may want to start opting for xz if you want smaller file archives.. In this guide, we're going to introduce you to xz compression, starting from basic examples to more specific and advanced usage. If tar recognizes the compression format, you don't need a flag: tar xvf *.tar.xz. If you need to decompress the input manually, for example because your tar is too old to recognize xz, or you need a special path: xz -cd *.tar.xz | tar xvf - Pipes are faster than making an uncompressed intermediate file, and use less disk space too!

By convention, the name of a tar archive compressed with xz ends with either .tar.xz or .txz.
