NAME    [Toc]    [Back]

     tcopy - copy and/or verify mag tapes

SYNOPSIS    [Toc]    [Back]

     tcopy [-cvx] [-s maxblk] [src [dest]]

DESCRIPTION    [Toc]    [Back]

     tcopy is designed to copy magnetic tapes.  The only  assumption made about
     the tape is that there are two tape marks at the end.  tcopy
with only a
     source tape (/dev/rst0 by default) specified will print  information about
     the  sizes  of  records and tape files.  If a destination is
specified a
     copy will be made of the source tape.  The blocking  on  the
destination
     tape  will  be  identical  to  that used on the source tape.
Copying a tape
     will yield the same output as if just printing the sizes.

     The options are as follows:

     -c      Copy src to dest and then verify that the two  tapes
are identical.


     -s maxblk
             Specify a maximum block size, maxblk.

     -v       Given the two tapes, src and dest, verify that they
are identical.


     -x      Output all informational messages  to  the  standard
error.  This
             option is useful when dest is /dev/stdout.
