       tp - manipulate tape archive

       tp [ key ] [ name ... ]

       Tp  saves  and  restores  files on DECtape or magtape.  Its actions are
       controlled by the key argument.  The key is a string of characters con‐
       taining  at  most one function letter and possibly one or more function
       modifiers.  Other arguments to the command are file or directory  names
       specifying  which  files are to be dumped, restored, or listed.  In all
       cases, appearance of a directory name refers to the files  and  (recur‐
       sively) subdirectories of that directory.

       The  function  portion  of the key is specified by one of the following

       r       The named files are written on the tape.   If  files  with  the
               same  names already exist, they are replaced.  `Same' is deter‐
               mined by string comparison, so `./abc' can never be the same as
               `/usr/dmr/abc' even if `/usr/dmr' is the current directory.  If
               no file argument is given, `.' is the default.

       u       updates the tape.  u is like r, but a file is replaced only  if
               its  modification  date  is  later  than the date stored on the
               tape; that is to say, if it has changed since it was dumped.  u
               is the default command if none is given.

       d       deletes the named files from the tape.  At least one name argu‐
               ment must be given.  This function is  not  permitted  on  mag‐

       x       extracts the named files from the tape to the file system.  The
               owner and mode are restored.  If no file argument is given, the
               entire contents of the tape are extracted.

       t       lists the names of the specified files.  If no file argument is
               given, the entire contents of the tape is listed.

       The following characters may be used in addition to  the  letter  which
       selects the function desired.

       m         Specifies magtape as opposed to DECtape.

       0,...,7   This modifier selects the drive on which the tape is mounted.
                 For DECtape, x is default; for magtape `0' is the default.

       v         Normally tp does its work silently.  The v  (verbose)  option
                 causes it to type the name of each file it treats preceded by
                 the function letter.  With the t function, v gives  more  in‐
                 formation about the tape entries than just the name.

       c         means  a  fresh  dump is being created; the tape directory is
                 cleared before beginning.  Usable only with r  and  u.   This
                 option  is assumed with magtape since it is impossible to se‐
                 lectively overwrite magtape.

       i         Errors reading and writing the tape are noted, but no  action
                 is  taken.   Normally,  errors  cause a return to the command

       f         Use the first named file, rather than a tape, as the archive.
                 This option is known to work only with x.

       w         causes  tp  to  pause before treating each file, type the in‐
                 dicative letter and the file name (as with v) and  await  the
                 user's  response.   Response  y  means  `yes', so the file is
                 treated.  Null response means `no', and  the  file  does  not
                 take  part  in  whatever  is  being  done.   Response x means
                 `exit'; the tp command  terminates  immediately.   In  the  x
                 function,  files  previously  asked about have been extracted
                 already.  With r, u, and d no change has  been  made  to  the


       ar(1), tar(1)

       Several;  the  non-obvious  one  is `Phase error', which means the file
       changed after it was selected for dumping but before it was dumped.

       A single file with several links to it is treated like several files.

       Binary-coded control information makes magnetic  tapes  written  by  tp
       difficult to carry to other machines; tar(1) avoids the problem.
