The Ftape Installation Guide
8.5.1.17: MTSEEK
zftape only. Seek to the specified block.
-
When using compression this results in reading some tape segments while
searching for the segment at the desired location which might require
more than one attempt because zftape has to guess the new position from
the compression ratio.
-
Without compression
MTSEEK
just modifies a variable and does
not result in tape motion.
-
Note that seeking always stays within the same volume, and the block
address is relative to the start of the current volume.
-
In variable block size mode the argument is interpreted as the desired
position measured in bytes. Maybe this is a bug.
- Example
-
seek to the 10th block, measured from the start of the current volume
-
mt -f /dev/nqft0 seek 10
