       tar - archiver

       tar key [ file ...  ]

       Tar  saves  and	restores  file trees.  It is most often used to transport a tree of files
       from one system to another.  The key is a string that contains at most one function letter
       plus optional modifiers.  Other arguments to the command are names of files or directories
       to be dumped or restored.  A directory name implies all the contained files and	subdirec-
       tories (recursively).

       The function is one of the following letters:

       c      Create a new archive with the given files as contents.

       x      Extract  the named files from the archive.  If a file is a directory, the directory
	      is extracted recursively.  Modes are restored if possible.  If no file argument  is
	      given,  extract the entire archive.  If the archive contains multiple entries for a
	      file, the latest one wins.

       t      List all occurrences of each file in the archive, or of all files if there  are  no
	      file arguments.

       r      The named files are appended to the archive.

       The modifiers are:

       v      (verbose)  Print	the  name  of  each file treated preceded by the function letter.
	      With t, give more details about the archive entries.

       f      Use the next argument as the name of the archive instead of  the	default  standard
	      input (for keys x and t) or standard output (for keys c and r).

       u      Use  the	next  (numeric)  argument as the user id for files in the output archive.
	      This is only useful when moving files to a non-Plan 9 system.

       g      Use the next (numeric) argument as the group id for files in the output archive.

       Tar can be used to copy hierarchies thus:

	      {cd fromdir; tar c .} | {cd todir; tar x}


       ar(1), bundle(1), tapefs(1)

       There is no way to ask for any but the last occurrence of a file.
       File path names are limited to 100 characters.
       The tar format allows specification of links and symbolic links, concepts foreign to  Plan
       9: they are ignored.
