Example: Copying the Transport File from Disk to Tape at the UNIX Source Computer

In order to copy a transport file from disk to tape at the source computer, issue the UNIX dd command. Here is an example:
dd if=tranfile of=/dev/tape1 bs=8000
dd
copies the specified input file to the specified output device.
if=tranfile
specifies the input file (or transport file).
of=/dev/tape1
specifies the output file (or tape device).
bs=8000
specifies the input file and output file block size as 8000.
See the UNIX dd(1) manual page for more details.
