- _a_n_s_i_t_a_p_e reads and writes magnetic tapes written in ANSI standard format
- (called ``Files-11'' by DEC). Tapes written by _a_n_s_i_t_a_p_e are labeled with
- the first six characters of the machine name by default. Actions are
- controlled by the _k_e_y argument. The _k_e_y is a string of characters
- containing at most one function letter. Other arguments to the command
- are a tape label and filenames specifying which files are to be written
- onto or extracted from the tape.
-
- Note that this version is designed to work with text files that is, those
- with no more than 2044 bytes without a newline character. Binary files
- are unlikely to be handled correctly on either creation or extraction.
-
- The function portion of the key is specified by one of the following
- letters:
-
- rrrr The named files are written at the end of the tape. The cccc
- function implies this.
-
- xxxx The named files are extracted from the tape. If no file argument
- is given, the entire contents of the tape are extracted. Note
- that if the tape has duplicated filenames, only the last file of
- a given name can be extracted.
-
- tttt The names of the specified files are listed each time they occur
- on the tape. If no file argument is given, all files on the tape
- are listed.
-
- cccc Create a new tape; writing begins at the beginning of the tape
- instead of after the last file. This command implies rrrr....
-
- The following characters may be used in addition to the letter that
- selects the function desired.
-
- ffff This argument allows the selection of a different tape device.
- The next word in the _k_e_y_a_r_g_s list is taken to be the full name of
- a local device on which to write the tape. The default is
- /_d_e_v/_t_a_p_e.
-
- nnnn The nnnn option allows the user to specify, as the next argument in
- the _k_e_y_a_r_g_s list, a control file containing the names of files to
- put on the tape. If the filename is '-', the control file will
- instead be read from standard input. The control file contains
- one line for each file placed on the tape. Each line has two
- names, the name of the file on the local machine and its name
- when placed on the tape. This allows for a convenient flattening

-
- of hierarchies when placing them on tape. If the second name is
- omitted, the UNIX filename will also be used on the tape. This
- argument can only be used with the rrrr and cccc functions.
-
- llll The llll option allows the user to specify the label to be placed on
- the tape. The next argument in the _k_e_y_a_r_g_s list is taken as the
- tape label, which will be space padded or truncated to six
- characters. This option is meaningless unless cccc is also
- specified.
-
- vvvv Normally _a_n_s_i_t_a_p_e works relatively silently. The vvvv (verbose)
- option causes it to type information about each file as it
- processes it.
-
- bbbb The bbbb option allows the user to select the block size to be used
- for the tape. By default, _a_n_s_i_t_a_p_e uses the maximum block size
- permitted by the ANSI standard, 2048. Some systems will permit a
- much larger block size, and if large files are being put on the
- tape, it may be advantageous to do so. _a_n_s_i_t_a_p_e takes the next
- argument of the _k_e_y_a_r_g_s list as the block size for the tape.
- Values below 18 or above 32k will be limited to that range. The
- standard scale factors b=512 and k=1024 are accepted.
-
- FFFF The FFFF flag allows _a_n_s_i_t_a_p_e to write ANSI 'D' format-fixed
- record-length tapes. The next two keyargs must be the recordsize
- and blocksize, with the same scale factors and range limits as
- the bbbb option. The files to be written by the FFFF flag must be in
- fixed format on the UNIX end-all lines should be _e_x_a_c_t_l_y rrrreeeeccccoooorrrrdddd----
- ssssiiiizzzzeeee bytes long plus a terminating newline (which will be
- discarded). Note that this is exactly the same format produced
- by _a_n_s_i_t_a_p_e when reading an ANSI 'D' format tape.
-
- _a_n_s_i_t_a_p_e will not copy directories, character or block special files,
- symbolic links, sockets, or binary executables. Attempts to put these on
- tape will result in warnings, and they will be skipped completely.

- A warning message will be generated when a record exceeds the maximum
- record length, and the affected file will be truncated.
-
- BBBBUUUUGGGGSSSS
- _a_n_s_i_t_a_p_e quietly truncates names longer than 17 characters.
-
- Multivolume tapes can be read (provided no files cross the volume
- boundary) but not written.
