Description
The tapedump command
dumps the contents of magnetic tapes according to the options specified.
Options include conversion from input format to user specified
output format, specification of input and output blocksize,
and the ability to specify that the dump begin at a specific start
block on the tape and proceed for a specified number of blocks.
tapedump takes the following options:
-a-
Convert from EBCDIC input to ASCII output.
-e-
Convert from ASCII input to EBCDIC output.
-h-
Display tape output in hexadecimal format.
-o-
Display tape output in octal format.
-b num[bkw]-
Set both input and output block size.
num is the number of blocks, which can
include b, k, or w to indicate the block size,
which correspond to 1024-, 512-, or 2-byte blocks,
respectively. If block size is not specified, b is
assumed.
-n num-
Specify dump of only num blocks.
-s num-
Skip num input records before starting dump.
-t num-
Specify which tape file to begin dump from, where
num is the tape file sequence number.
tape_device-
The input tape device.
output_file-
The output filename; standard output is the default.
The output file may be specified to be another tape device.
Examples
This command reads a tape starting at block 400 and outputs
the results in hexadecimal format into a user specified file
called /tmp/hex.dump:
tapedump -b400 -h /dev/rct0 /tmp/hexdump
This command reads an EBCDIC tape and converts the standard output
to ASCII:
tapedump -a /dev/rct0
