NAME

mt − magnetic tape manipulating program

SYNOPSIS

mt [ −t /dev/tapename ] command [ count ]

DESCRIPTION

Mt is used to give commands to a half-inch magnetic tape drive.  By default, mt performs the requested operation once.  Operations may be performed multiple times by specifying count.

The default tape device uses the no-rewind device.  No filemark is written to the no-rewind device on close. 

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

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

fsf Forward space count files. 

fsr Forward space count records. 

bsf Backspace count files. 

bsr Backspace count records. 

rewind
Rewind the tape (Count is ignored.) 

status
Print status information about the tape unit. (Count is ignored.) 

help Print command usage information about the command.  (Count is ignored.) 

Mt returns a 0 exit status when the operations were successful, a 1 if a command was unrecognized, and a 2 if a operation failed.  Mt without any arguments defaults to help.
