       ansitape - ANSI standard tape handler

       ansitape [key] [keyargs] [files]

       Ansitape  reads	and  writes  magnetic  tapes  written  in  ANSI  standard  format (called
       ``Files-11'' by DEC).  Tapes written by ansitape are labeled with the first  6  characters
       of the machine name by default.	Actions are controlled by the key argument.  The key is a
       string of characters containing at most one function letter.  Other arguments to the  com-
       mand  are  a  tape  label  and file names specifying which files are to be written onto or
       extracted from the tape.

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

       r       The named files are written at the end of the tape.  The c function implies this.

       x       The named files are extracted from the tape.  If no file argument  is  given,  the
	       entire  contents  of  the tape is extracted.  Note that if the tape has duplicated
	       file names, only the last file of a given name can be extracted.

       t       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.

       c       Create  a  new  tape; writing begins at the beginning of the tape instead of after
	       the last file.  This command implies r.

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

       f       This  argument  allows the selection of a different tape device.  The next word in
	       the keyargs list is taken to be the full name of a device to write  the	tape  on.
	       The default is /dev/rmt12.

       n       The  n option allows the user to specify as the next argument in the keyargs list,
	       a control file containing the names of files to put on the tape.  If the file name
	       is  '-', the control file will, instead, be read from standard input.  The control
	       file contains one line for each file to be placed on the tape.  Each line has  two
	       names,  the name of the file on the local machine, and the name it is to have when
	       placed on the tape.  This allows for more  convenient  flattening  of  hierarchies
	       when placing them on tape.  If the second name is omitted, the UNIX file name will
	       be used on the tape also.  This argument can only be used with the r and  c  func-

       l       The  l  option allows the user to specify the label to be placed on the tape.  The
	       next argument in the keyargs list is taken as the tape label, which will be  space
	       padded  or  truncated  to  six characters.  This option is meaningless unless c is
	       also specified.

       v       Normally ansitape works relatively silently.  The v (verbose) option causes it  to
	       type information about each file as it processes it.

       b       The  b option allows the user to select the blocksize to be used for the tape.  By
	       default, ansitape uses the maximum block size  permitted  by  the  ANSI	standard,
	       2048.   Some  systems  will permit a much large block size, and if large files are
	       being put on the tape it may be advantageous to do so.	Ansitape  will	take  the
	       next  argument of the keyargs list as the blocksize 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.

       Ansitape  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.

       Ansitape quietly truncates names longer than 17 characters.
       ANSI 'f' format files can be read but not written.
       Multivolume tapes can not be handled.
