The default tape device to operate on is taken from the file /usr/include/sys/mtio.h when mt is compiled. It can be overridden by giving a device file name in the environment variableTAPE or by a command line option (see below), which also overrides the environment variable.
The device must be either a character special file or a remote tape drive. To use a tape drive on another machine as the archive, use a file name that starts with 'HOSTNAME:'. The hostname can be preceded by a username and an '@' to access the remote tape drive as that user, if you have permission to do so (typically an entry in that user's '~/.rhosts' file).
The available operations are listed below. Unique abbreviations are accepted. Not all operations are available on all systems, or work on all types of tape drives. Some operations optionally take a repeat count, which can be given after the operation name and defaults to 1.
Forward space count files. The tape is positioned on the first block of the next file.
bsf
Backward space count files. The tape is positioned on the first block of the next file.
fsr
Forward space count records.
bsr
Backward space count records.
bsfm
Backward space count file marks. The tape is positioned on the beginning-of-the-tape side of the file mark.
fsfm
Forward space count file marks. The tape is positioned on the beginning-of-the-tape side of the file mark.
asf
Absolute space to file number count. Equivalent to rewind followed by fsf count.
seek
Seek to block number count.
eom
Space to the end of the recorded media on the tape (for appending files onto tapes).
rewind
Rewind the tape.
offline, rewoffl
Rewind the tape and, if applicable, unload the tape.
status
Print status information about the tape unit.
retension
Rewind the tape, then wind it to the end of the reel, then rewind it again.
erase
Erase the tape.
Options
-f, --file=device
Use device as the file name of the tape drive to operate on. To use a tape drive on another machine, use a file name that starts with 'HOSTNAME:'. The hostname can be preceded by a username and an '@' to access the remote tape drive as that user, if you have permission to do so (typically an entry in that user's '~/.rhosts' file).
--rsh-command=command
Notifies mt that it should use command to communicate with remote devices instead of /usr/bin/ssh or /usr/bin/rsh.
-V, --version
Print the version number of mt.
Exit Status
mt exits with a status of 0 if the operation succeeded, 1 if the operation or device name given was invalid, or 2 if the operation failed.
mt (控制磁帶設備)
在類似Unix的操作系統上，mt命令控制磁帶設備。

mt 描述
默認的磁帶設備進行操作，從文件中提取/usr/include/sys/mtio.h當MT被編譯。可以通過在環境變量 TAPE中指定設備文件名或使用命令行選項（請參見下文）來覆蓋它，該選項也將覆蓋環境變量。
該設備必須是字符專用文件或遠程磁帶驅動器。若要將另一臺計算機上的磁帶機用作存檔，請使用以“ HOSTNAME： ”開頭的文件名。主機名前面可以有一個用戶名和一個@，以該用戶的身份訪問遠程磁帶驅動器（如果您具有這樣做的權限）（通常是該用戶的?/ .rhosts文件中的一個條目）。
下面列出了可用的操作。接受唯一的縮寫。并非所有操作在所有系統上均可用，或在所有類型的磁帶機上均可用。某些操作可以選擇重復計數，該計數可以在操作名稱之后指定，默認為1。
