NAME
       mt - magnetic tape manipulating program

SYNOPSIS
       mt [ -f _t_a_p_e_n_a_m_e ] _c_o_m_m_a_n_d [ _c_o_u_n_t ]

DESCRIPTION
       _M_t  is  used to give commands to a magnetic tape drive.  If a tape name
       is not specified, the environment variable TAPE is used;  if TAPE  does
       not exist, _m_t uses the device _/_d_e_v_/_r_m_t_1_2.  Note that _t_a_p_e_n_a_m_e must ref‐
       erence a raw (not block) tape  device.   By  default  _m_t  performs  the
       requested  operation  once.  Operations may be performed multiple times
       by specifying _c_o_u_n_t.

       The available commands are listed below.  Only as  many  characters  as
       are required to uniquely identify a command need be specified.

       eof, weof
              Write  _c_o_u_n_t  end-of-file  marks  at the current position on the
              tape.

       fsf    Forward space _c_o_u_n_t files.

       fsr    Forward space _c_o_u_n_t records.

       bsf    Back space _c_o_u_n_t files.

       bsr    Back space _c_o_u_n_t records.

       rewind Rewind the tape (_C_o_u_n_t is ignored).

       offline, rewoffl
              Rewind the tape and place  the  tape  unit  off-line  (_C_o_u_n_t  is
              ignored).

       status Print status information about the tape unit.

       _M_t  returns a 0 exit status when the operation(s) were successful, 1 if
       the command was unrecognized, and 2 if an operation failed.
