.TH AR 1 .SH NAME ar \- archive maintainer .SH SYNOPSIS .B ar .I key [ .I posname ] .I afile [ .I file ... ] .SH DESCRIPTION .I Ar maintains groups of files combined into a single archive file, .IR afile . The main use of .I ar is to produce and manipulate UNIX archive files, for instance to create program packages for Debian Linux. Note that only .IR iar (10.1) can manage archives used as object file libraries by the Inferno and Plan 9 loaders. .PP .I Key is one character from the set .BR drqtpmx , optionally concatenated with one or more of .BR vuaibclo . The .I files are constituents of the archive .IR afile . The meanings of the .I key characters are: .TP .B d Delete .I files from the archive file. .TP .B r Replace .I files in the archive file, or add them if missing. Optional modifiers are .RS .PD0 .TP .B u Replace only files with modified dates later than that of the archive. .TP .B a Place new files after .I posname in the archive rather than at the end. .TP .BR b " or " i Place new files before .I posname in the archive. .RE .PD .TP .B q Quick. Append .I files to the end of the archive without checking for duplicates. Avoids quadratic behavior in .LR "for (i in *.v) ar r lib.a $i" . .TP .B t List a table of contents of the archive. If names are given, only those files are listed. .TP .B p Print the named files in the archive. .TP .B m Move the named files to the end or elsewhere, specified as with .LR r . .TP .B o Preserve the access and modification times of files extracted with the .B x command. .TP .B x Extract the named files. If no names are given, all files in the archive are extracted. In neither case does .B x alter the archive file. .TP .B v Verbose. Give a file-by-file description of the making of a new archive file from the old archive and the constituent files. With .BR p , precede each file with a name. With .BR t , give a long listing of all information about the files, somewhat like a listing by .IR ls (1), showing .br .ns .IP .B mode uid/gid size date name .TP .B c Create. Normally .I ar will create a new archive when .I afile does not exist, and give a warning. Option .B c discards any old contents and suppresses the warning. .SH EXAMPLE .TP .L ar cr arch.a manifest *.tar.gz Replace the contents of .L arch.a with the .B manifest file and all the .IR gzip (1)'d .I tar files in the current directory. .SH FILES .TF /tmp/art.*.* .TP .B /tmp/art.*.* temporaries .SH SOURCE .B /appl/cmd/ar.b .SH "SEE ALSO" .IR 2l (10.1), .IR iar (10.1), .IR ar (10.6) .SH BUGS If the same file is mentioned twice in an argument list, it may be put in the archive twice. .br The file format used by this command is taken from UNIX, and makes some invalid assumptions, for instance that user IDs are numeric.
