22:
23: OOOOppppttttiiiioooonnnnssss
24: The following options are available:
25:
26: ----cccc Creates a new archive; writing begins at the
27: beginning of the archive, instead of after the
28: last file.
29:
30: ----rrrr Writes names files to the end of the archive.
31:
32: ----tttt Lists the names of all of the files in the
33: archive.
34:
35: ----uuuu Causes named files to be added to the archive if
36: they are not already there, or have been modified
37: since last written into the archive. This implies
38: the ----rrrr option.
39:
40: ----xxxx Extracts named files from the archive. If a named
41: file matches a directory whose contents had been
42: written onto the archive, that directory is
43: recursively extracted. If a named file in the
44: archive does not exist on the system, the file is
45: create with the same mode as the one in the
46: archive, except that the set-user-id and get-
47: group-id modes are not set unless the user has
48: appropriate privileges.
49:
50: If the files exist, their modes are not changed except as
51: described above. The owner, group and modification time are
52: restored if possible. If no _f_i_l_e_n_a_m_e argument is given, the
53: entire contents of the archive is extracted. Note that if
54: several files with the same name are in the archive, the
55: last one will overwrite all earlier ones.
56:
57: ----bbbb Causes _u_s_t_a_r to use the next argument on the
58: command line as the blocking factor for tape
59: records. The default is 1; the maximum is 20.

71:
72:
73:
74: This option should only be used with raw magnetic
75: tape archives. Normally, the block size is
76: determined automatically when reading tapes.
77:
78: ----ffff Causes _u_s_t_a_r to use the next argument on the
79: command line as the name of the archive instead of
80: the default, which is usually a tape drive. If ----
81: is specified as a filename _u_s_t_a_r writes to the
82: standard output or reads from the standard input,
83: whichever is appropriate for the options given.
84: Thus, _u_s_t_a_r can be used as the head or tail of a
85: pipeline.
86:
87: ----llll Tells _u_s_t_a_r to report if it cannot resolve all of
88: the links to the files being archived. If ----llll is
89: not specified, no error messages are written to
90: the standard output. This modifier is only valid
91: with the ----cccc, ----rrrr and ----uuuu options.
92:
93: ----mmmm Tells _u_s_t_a_r not to restore the modification times.
94: The modification time of the file will be the time
95: of extraction. This modifier is invalid with th
96: ----tttt option.
97:
98: ----oooo Causes extracted files to take on the user and
99: group identifier of the user running the program
100: rather than those on the archive. This modifier
101: is only valid with the ----xxxx option.
102:
103: ----vvvv Causes _u_s_t_a_r to operate verbosely. Usually, _u_s_t_a_r
104: does its work silently, but the vvvv modifier causes
105: it to print the name of each file it processes,
106: preceded by the option letter. With the ----tttt
107: option, vvvv gives more information about the archive
108: entries than just the name.
109:
110: ----wwww Causes _u_s_t_a_r to print the action to be taken,
111: followed by the name of the file, and then wait
112: for the user's confirmation. If a word beginning
113: with yyyy is given, the action is performed. Any
114: other input means "no". This modifier is invalid
115: with the ----tttt option.
116:
117: FFFFIIIILLLLEEEESSSS
118: /dev/tty used to prompt the user for information when the
119: ----iiii or ----yyyy options are specified.
