NAME
tcopy - copy a magnetic tape
SYNOPSIS
/usr/ucb/tcopy source [ destination ]
DESCRIPTION
tcopy copies the magnetic tape mounted on the tape drive specified by the source argument. The only assumption made about the contents of a tape is that there are two tape marks at the end. When only a source drive is specified, tcopy scans the tape, and displays information about the sizes of records and tape files. If a destination is specified, tcopy makes a copies the source tape onto the destination tape, with blocking preserved. As it copies, tcopy produces the same output as it does when only scanning a tape.

NOTES
tcopy will only run on systems supporting an associated set of ioctl(2) requests.
