The tar command is a powerful utility used for archiving and compressing files and directories in Unix-like operating systems. The most commonly used options are:

  • c: Create a new archive.
  • x: Extract files from an archive.
  • t: List the contents of an archive.
  • v: Verbosely show the file’s details (verbose mode).
  • f: Use the following archive file (followed by the filename).
  • z: Filter the archive through gzip (typically used with .tar.gz or .tgz files).
  • j: Filter the archive through bzip2 (typically used with .tar.bz2 files).
  • J: Filter the archive through xz (typically used with .tar.xz files).
  • r: Append files to the end of an archive.
  • u: Update files in the archive (add files if they are newer than the existing archive files).
  • d: Compare contents of the archive against files on the filesystem.
  • --delete: Delete files from an archive.
