GETTAR(1) GETTAR(1)
NAME
gettar, lstar, puttar - tar archive utilities
SYNOPSIS
gettar [ -k ] [ -v ] [ -R ] [ name ... ]
lstar
puttar [ file ... ]
DESCRIPTION
These commands manage POSIX.1 tar archives in Inferno.
Gettar reads a tar file from standard input and unpacks the
contents into the current directory tree. By default,
gettar converts absolute path names, including names start-
ing with `#', into names relative to the current directory;
the -R option extracts such names as-is. The -k option
tells gettar to keep existing files rather than overwriting
them with files from the archive. The -v option causes
gettar to print on standard error the names of files
extracted. Finally, listing one or more names as arguments
will extract only those files.
Lstar reads a tar file from standard input and lists the
files contained therein, one per line, with four space-
separated fields giving the file name, modification time (in
seconds since the epoch), size (in bytes), and a constant 0
(the place holder for a checksum). The format is the same
as that produced by du -n -t.
Puttar writes a tar file to standard output that contains
each file, and its substructure if it is a directory. Given
no arguments, puttar instead reads a list of file names from
standard input and includes each file or directory named; it
does not copy directory substructure.
EXAMPLE
The following commands create a tar file with two files
test.b and srv.b:
$ cat tarlist
test.b
srv.b
$ puttar <tarlist >test.tar
$ lstar <test.tar
test.b 867178082 1104 0
srv.b 866042662 3865 0
