SYNOPSIS

9       tp [ key ] [ name ... ]
10

DESCRIPTION

12       Tp  saves  and  restores  files on DECtape or magtape.  Its actions are
13       controlled by the key argument.  The key is a string of characters con‐
14       taining  at  most one function letter and possibly one or more function
15       modifiers.  Other arguments to the command are file or directory  names
16       specifying  which  files are to be dumped, restored, or listed.  In all
17       cases, appearance of a directory name refers to the files  and  (recur‐
18       sively) subdirectories of that directory.
19
20       The  function  portion  of the key is specified by one of the following
21       letters:
22
23       r       The named files are written on the tape.   If  files  with  the
24               same  names already exist, they are replaced.  `Same' is deter‐
25               mined by string comparison, so `./abc' can never be the same as
26               `/usr/dmr/abc' even if `/usr/dmr' is the current directory.  If
27               no file argument is given, `.' is the default.
28
29       u       updates the tape.  u is like r, but a file is replaced only  if
30               its  modification  date  is  later  than the date stored on the
31               tape; that is to say, if it has changed since it was dumped.  u
32               is the default command if none is given.
33
34       d       deletes the named files from the tape.  At least one name argu‐
35               ment must be given.  This function is  not  permitted  on  mag‐
36               tapes.
37
38       x       extracts the named files from the tape to the file system.  The
39               owner and mode are restored.  If no file argument is given, the
40               entire contents of the tape are extracted.
41
42       t       lists the names of the specified files.  If no file argument is
43               given, the entire contents of the tape is listed.
44
45       The following characters may be used in addition to  the  letter  which
46       selects the function desired.
47
48       m         Specifies magtape as opposed to DECtape.
49
50       0,...,7   This modifier selects the drive on which the tape is mounted.
51                 For DECtape, x is default; for magtape `0' is the default.
52
53       v         Normally tp does its work silently.  The v  (verbose)  option
54                 causes it to type the name of each file it treats preceded by
55                 the function letter.  With  the  t  function,  v  gives  more
56                 information about the tape entries than just the name.
57
58       c         means  a  fresh  dump is being created; the tape directory is
59                 cleared before beginning.  Usable only with r  and  u.   This
60                 option  is  assumed  with  magtape  since it is impossible to
61                 selectively overwrite magtape.
62
63       i         Errors reading and writing the tape are noted, but no  action
64                 is  taken.   Normally,  errors  cause a return to the command
65                 level.
66
67       f         Use the first named file, rather than a tape, as the archive.
68                 This option is known to work only with x.
69
70       w         causes  tp  to  pause  before  treating  each  file, type the
71                 indicative letter and the file name (as with v) and await the
72                 user's  response.   Response  y  means  `yes', so the file is
73                 treated.  Null response means `no', and  the  file  does  not
74                 take  part  in  whatever  is  being  done.   Response x means
75                 `exit'; the tp command  terminates  immediately.   In  the  x
76                 function,  files  previously  asked about have been extracted
77                 already.  With r, u, and d no change has  been  made  to  the
78                 tape.

FILES

81       /dev/tap?
82       /dev/mt?
83

SEE ALSO

85       ar(1), tar(1)
86

DIAGNOSTICS

88       Several;  the  non-obvious  one  is `Phase error', which means the file
89       changed after it was selected for dumping but before it was dumped.
90

BUGS

92       A single file with several links to it is treated like several files.
93
94       Binary-coded control information makes magnetic  tapes  written  by  tp
95       difficult to carry to other machines; tar(1) avoids the problem.
