Introduction
This cheat sheet provides a quick reference for some common mt
(Magnetic Tape Control) commands and concepts. mt
is a command-line utility used to control and manipulate magnetic tape drives on Unix-like operating systems.
mt
Concepts
Device Identification
mt
requires specifying the tape drive device as an argument.
- Identify the tape drive device:
mt -f /dev/st0 status
Tape Movement
You can use mt
to move the tape forward, backward, rewind, and more.
Rewind the tape:
mt -f /dev/st0 rewind
Move the tape forward by a specified number of files:
mt -f /dev/st0 fsf 3
Move the tape backward by a specified number of files:
mt -f /dev/st0 bsf 2
Tape Status
mt
provides information about the tape drive and current tape status.
- Display the status of the tape drive:
mt -f /dev/st0 status
Tape Marks
You can write and skip tape marks.
Write a file tape mark:
mt -f /dev/st0 weof
Skip a file tape mark:
mt -f /dev/st0 eof
Tape Density
mt
allows you to set tape density.
- Set the tape density to 6250 BPI:
mt -f /dev/st0 density 6250
mt
Command-Line
Identify the tape drive device:
mt -f /dev/st0 status
Rewind the tape:
mt -f /dev/st0 rewind
Move the tape forward by a specified number of files:
mt -f /dev/st0 fsf 3
Move the tape backward by a specified number of files:
mt -f /dev/st0 bsf 2
Display the status of the tape drive:
mt -f /dev/st0 status
Write a file tape mark:
mt -f /dev/st0 weof
Skip a file tape mark:
mt -f /dev/st0 eof
Set the tape density to 6250 BPI:
mt -f /dev/st0 density 6250
Conclusion
This cheat sheet covers some common mt
(Magnetic Tape Control) commands and concepts. mt
is a useful tool for controlling and managing magnetic tape drives on Unix-like operating systems, making it valuable for backup and archival tasks; refer to the official mt
documentation for more in-depth information and advanced usage.
