Tar tutorial

November 1st, 2009 No comments

Create, Extract, See Contents

The tar program takes one of three funcion command line arguments (there are two others I won’t talk about).

  • c – to create a tar file, writing the file starts at the beginning.
  • t – table of contents, see the names of all files or those specified in other command line arguments.
  • x – extract (restore) the contents of the tar file.

Compression, Verbose, File specified

In addition to a function command line argument the arguments below are useful. I usually use z and f all the time, and v when creating/extracting.

  • f — specifies the filename (which follows the f) used to tar into or to tar out from; see the examples below.
  • z — use zip/gzip to compress the tar file or to read from a compressed tar file.
  • v — verbose output, show, e.g., during create or extract, the files being stored into or restored from the tar file.

Examples

To tar all .cc and .h files into a tar file named foo.tgz use:

    tar cvzf foo.tgz *.cc *.h

To see a tar file’s table of contents use:

   tar tzf foo.tgz

To extract the contents of a tar file use:

    tar xvzf foo.tgz
