.TH GETTAR 1 .SH NAME gettar, lstar, puttar \- tar archive utilities .SH SYNOPSIS .B gettar [ .B -k ] [ .B -v ] [ .B -R ] [ .IR name " ..." ] .br .B lstar .br .B puttar [ .I file ... ] .SH DESCRIPTION These commands manage POSIX.1 tar archives in Inferno. .PP .I Gettar reads a tar file from standard input and unpacks the contents into the current directory tree. By default, .I gettar converts absolute path names, including names starting with .LR # , into names relative to the current directory; the .B -R option extracts such names as-is. The .B -k option tells .I gettar to keep existing files rather than overwriting them with files from the archive. The .B -v option causes .I gettar to print on standard error the names of files extracted. Finally, listing one or more .I names as arguments will extract only those files. .PP .I 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 .BR "du -n -t" . .PP .I Puttar writes a tar file to standard output that contains each .IR file , and its substructure if it is a directory. Given no arguments, .I puttar instead reads a list of file names from standard input and includes each file or directory named; it does not copy directory substructure. .SH EXAMPLE The following commands create a tar file with two files .B test.b and .BR srv.b : .IP .EX $ cat tarlist test.b srv.b $ puttar <tarlist >test.tar $ lstar <test.tar test.b 867178082 1104 0 srv.b 866042662 3865 0 .EE .SH SOURCE .B /appl/cmd/gettar.b .br .B /appl/cmd/lstar.b .br .B /appl/cmd/puttar.b .SH SEE ALSO .IR tarfs (4)
