MT(1)							      General Commands Manual							     MT(1)

NAME

       mt - magnetic tape manipulating program

SYNOPSIS

       mt [ -f tapename ] command [ count ]

DESCRIPTION

       Mt  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, mt uses the device /dev/rmt12.  Note that tapename must reference a raw (not block) tape device.  By  default  mt  performs
       the requested operation once.  Operations may be performed multiple times by specifying count.

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

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

       fsf    Forward space count files.

       fsr    Forward space count records.

       bsf    Back space count files.

       bsr    Back space count records.

       rewind Rewind the tape (Count is ignored).

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

       status Print status information about the tape unit.

       cacheon
	      Enable the readahead/writebehind cache on the tape unit.

       cacheoff
	      Turn off the readahead/writebehind cache on the tape unit.

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

       The cacheon and cacheoff commands currently only apply to the TMSCP driver and then only for certain drives such as the TU81+.  No error is
       produced by the TMSCP driver if the cache commands are used.  Other drivers will return an error code  since  they  do  not  recognize  the
       MTCACHE and MTNOCACHE functions codes.  See mtio(4).
