<p>New page: TP(1) UNIX Programmer&#039;s Manual TP(1) == NAME == tp - manipulate tape archive == SYNOPSIS == tp [ key ] [ name ... ] == DESCRIPTION == _T_p ...</p> <p><b>New page</b></p><div>TP(1) UNIX Programmer's Manual TP(1)<br /> <br /> <br /> <br /> == NAME ==<br /> tp - manipulate tape archive<br /> <br /> == SYNOPSIS ==<br /> tp [ key ] [ name ... ]<br /> <br /> == DESCRIPTION ==<br /> _T_p saves and restores files on DECtape or magtape. Its<br /> actions are controlled by the _k_e_y argument. The key is a<br /> string of characters containing at most one function letter<br /> and possibly one or more function modifiers. Other argu-<br /> ments to the command are file or directory names specifying<br /> which files are to be dumped, restored, or listed. In all<br /> cases, appearance of a directory name refers to the files<br /> and (recursively) subdirectories of that directory.<br /> <br /> The function portion of the key is specified by one of the<br /> following letters:<br /> <br /> r The named files are written on the tape. If files<br /> with the same names already exist, they are<br /> replaced. `Same' is determined by string com-<br /> parison, so `./abc' can never be the same as<br /> `/usr/dmr/abc' even if `/usr/dmr' is the current<br /> directory. If no file argument is given, `.' is the<br /> default.<br /> <br /> u updates the tape. u is like r, but a file is<br /> replaced only if its modification date is later than<br /> the date stored on the tape; that is to say, if it<br /> has changed since it was dumped. u is the default<br /> command if none is given.<br /> <br /> d deletes the named files from the tape. At least one<br /> name argument must be given. This function is not<br /> permitted on magtapes.<br /> <br /> x extracts the named files from the tape to the file<br /> system. The owner and mode are restored. If no<br /> file argument is given, the entire contents of the<br /> tape are extracted.<br /> <br /> t lists the names of the specified files. If no file<br /> argument is given, the entire contents of the tape<br /> is listed.<br /> <br /> The following characters may be used in addition to the<br /> letter which selects the function desired.<br /> <br /> m Specifies magtape as opposed to DECtape.<br /> <br /> 0,...,7 This modifier selects the drive on which the tape<br /> is mounted. For DECtape, x is default; for<br /> magtape `0' is the default.<br /> <br /> v Normally _t_p does its work silently. The v (ver-<br /> bose) option causes it to type the name of each<br /> file it treats preceded by the function letter.<br /> With the t function, v gives more information<br /> about the tape entries than just the name.<br /> <br /> c means a fresh dump is being created; the tape<br /> directory is cleared before beginning. Usable<br /> only with r and u. This option is assumed with<br /> magtape since it is impossible to selectively<br /> overwrite magtape.<br /> <br /> i Errors reading and writing the tape are noted, but<br /> no action is taken. Normally, errors cause a<br /> return to the command level.<br /> <br /> f Use the first named file, rather than a tape, as<br /> the archive. This option is known to work only<br /> with x.<br /> <br /> w causes _t_p to pause before treating each file, type<br /> the indicative letter and the file name (as with<br /> v) and await the user's response. Response y<br /> means `yes', so the file is treated. Null<br /> response means `no', and the file does not take<br /> part in whatever is being done. Response x means<br /> `exit'; the _t_p command terminates immediately. In<br /> the x function, files previously asked about have<br /> been extracted already. With r, u, and d no<br /> change has been made to the tape.<br /> <br /> == FILES ==<br /> /dev/tap?<br /> /dev/mt?<br /> <br /> == SEE ALSO ==<br /> [[32v 1m ar|ar(1)]], [[32v 1m tar|tar(1)]]<br /> <br /> == DIAGNOSTICS ==<br /> Several; the non-obvious one is `Phase error', which means<br /> the file changed after it was selected for dumping but<br /> before it was dumped.<br /> <br /> == BUGS ==<br /> A single file with several links to it is treated like<br /> several files.<br /> <br /> Binary-coded control information makes magnetic tapes writ-<br /> ten by _t_p difficult to carry to other machines; _t_a_r(1)<br /> avoids the problem.<br /> [[Category:32v man section 1]]</div>
