the +.Nm +program creates, adds files to, or extracts files from an archive file +in +.Nm +format, called a +.Ar tarfile . +A +.Ar tarfile +is often a magnetic tape, but can be a floppy diskette or any +regular disk file. +.Pp +The first argument word of the +.Nm +command line is usually a command word of bundled function and modifier +letters, optionally preceded by a dash; +it must contain exactly one function letter from the set +.Cm A , +.Cm c , +.Cm d , +.Cm r , +.Cm t , +.Cm u , +.Cm x , +for +.Em append , +.Em create , +.Em difference , +.Em replace , +.Em table of contents , +.Em update , +and +.Em extract +(further described below). +The command word can also contain other function modifiers described below, +some of which will take arguments from the command line in the order they +are specified in the command word (review the +.Sx EXAMPLES +section). +Functions and function modifiers can also be specified +with the GNU argument convention (preceded by two dashes, one function or +modifier per word. +Command-line arguments that specify files to +add to, extract from, or list from an archive may be given as shell +pattern matching strings. +.Sh FUNCTIONS +Exactly one of the following functions must be specified. +.Pp +.Bl -tag -width "--concatenate" -compact +.It Fl A +.It Fl -catenate +.It Fl "-concatenate" +Append the contents of named file, which must itself be a +.Nm +archive, +to the end of the archive (erasing the old end-of-archive block). +This has the effect of adding the files contained in the named file to +the first archive, rather than adding the second archive as an element +of the first. +.Em Note : +This option requires a rewritable +.Ar tarfile , +and therefore does not work on quarter-inch cartridge tapes. +.It Fl c +.It Fl -create +Create a new archive (or truncates an old one) and writes the named files +to it. +.It Fl d +.It Fl -diff +.It Fl -compare +Find differences between files in the archive and corresponding files in +the file system. +.It Fl -delete +Delete named files from the archive. +(Does not work on quarter-inch tapes). +.It Fl r +.It Fl -append +Append files to the end of an archive. +(Does not work on quarter-inch tapes). +.It Fl t +.It Fl -list +List the contents of an archive; if +.Ar filename +arguments are given, only those +files are listed, otherwise the entire table of contents is listed. +.It Fl u +.It Fl -update +Append the named files if the on-disk version has a modification date +more recent than their copy in the archive (if any). +Does not work on quarter-inch tapes. +.It Fl x +.It Fl -extract +.It Fl -get +Extract files from an archive. +The owner, modification time, and file permissions are restored, if possible. +If no +.Ar file +arguments are given, extract all the files in the archive. +If a +.Ar filename +argument matches the name of a directory on the tape, that directory and +its contents are extracted (as well as all directories under that directory). +If the archive contains multiple entries corresponding to the same file +(see the +.Fl -append +command above), the last one extracted will overwrite all earlier versions. +.El +.Sh OPTIONS +The other options to +.Nm +may be combined arbitrarily; single-letter options may be bundled in with +the command word. +Verbose options which take arguments will be +followed by the argument; single-letter options will consume +successive command line arguments (see the +.Sx EXAMPLES +below). +.Pp +.Bl -tag -width "--preserve-permissions" -compact +.It Fl -help +Prints a message listing and briefly describing all the command +options to +.Nm . +.It Fl -atime-preserve +Restore the access times on files which are written to tape (note that +this will change the inode-change time!). +.It Fl b +.It Fl -block-size Ar number +Sets the block size for reading or writing to +.Ar number +* 512-byte blocks. +.It Fl B +.It Fl -read-full-blocks +Re-assemble short reads into full blocks (for reading +.Bx 4.2 +pipes). +.It Fl C Ar directory +.It Fl -directory Ar directory +Change to +.Ar directory +before processing the remaining arguments. +.It Fl -checkpoint +Print number of buffer reads/writes while reading/writing the archive. +.It Fl f Xo +.Oo Ar hostname : Oc Ns Ar file +.Xc +.It Fl -file Xo +.Oo Ar hostname : Oc Ns Ar file +.Xc +Read or write the specified +.Ar file +(default is +.Pa /dev/sa0 ) . +If a +.Ar hostname +is specified, +.Nm +will use +.Xr rmt 8 +to read or write the specified +.Ar file +on a remote machine. +.Dq Ar - +may be used as a filename, for reading +or writing to/from stdin/stdout. +.It Fl -force-local +Archive file is local even if it has a colon. +.It Fl F Ar file +.It Fl -info-script Ar file +.It Fl -new-volume-script Ar file +Run a script at the end of each archive volume (implies +.Fl M ) . +.It Fl -fast-read +Stop after all non-wildcard extraction targets have been found +in the archive. +.It Fl G +.It Fl -incremental +Create/list/extract old GNU-format incremental backup. +.It Fl g Ar file +.It Fl -listed-incremental Ar file +Create/list/extract new GNU-format incremental backup. +.It Fl h +.It Fl -dereference +Don't write symlinks as symlinks;
