script assistance with shift J

Hey all, I need some assistance. I'm writing a script to eject tapes from a tape library, but the library is not a queued system and can only eject 15 tapes at a time.

I added paste -d : -s so that it goes through full_tapes and puts each media_id on one line separated by the :.

Now I'm stuck on how to I separate each set of 15 into multiple lines, if I have over 15 tapes. Otherwise, this works great if I only have to eject 15 tapes.

Here is what I have so far.

Code:

#!/usr/bin/ksh

#################################
# DEFINE FILES & VARIABLES HERE #
#################################

TAPE="/usr/openv/netbackup/bin/lto-fullt.mail"
FULL_TAPES"/usr/openv/netbackup/bin/full_tapes"

#####################
# BEGINNING OF MAIN #
#####################

for i in "${TAPE}"
do
   cat $TAPE |awk '{ print $1 }' | paste -d : -s > full_tapes
done

for j in "${FULL_TAPES}"
do
   /usr/openv/volmgr/bin/vmchange -res -multi_eject -w -verbose -rn 0 -rt TLD -rh bkup2 ml $FULL_TAPES


if [ "j" -eq 0 ] ; then
            echo "$FULL_TAPES Ejected successfully "
        else
             echo "$FULL_TAPES Eject failed"
         fi
       else
            echo "$FULL_TAPES not in library "
     fi
  fi
done

The full_tapes media_id looks like.

Code:

After paste -d : -s

Code:

tcopy

TCOPY(1)						    BSD General Commands Manual 						  TCOPY(1)

NAME

     tcopy -- copy and/or verify mag tapes

SYNOPSIS

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

DESCRIPTION

     The tcopy utility is designed to copy magnetic tapes.  The only assumption made about the tape layout is that there are two sequential EOF
     marks at the end.	By default, the tcopy utility will print information about the sizes of records and files found on the /dev/sa0 tape, or
     on the tape specified by the src argument.  If a destination tape is also specified by the dest argument, a copy of the source tape will be
     made.  The blocking on the destination tape will be identical to that used on the source tape.  Copying a tape will yield the same program
     output as if just printing the sizes.

     The following options are available:

     -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 instead of the standard output.  This option is useful when dest is given
		as /dev/stdout.

SEE ALSO

     mt(1), mtio(4)

HISTORY

     The tcopy command appeared in 4.3BSD.

BUGS

     Writing an image of a tape to a file does not preserve much more than the raw data.  Block size(s) and tape EOF marks are lost which would
     otherwise be preserved in a tape-to-tape copy.

     End of data (EOD) is determined by two sequential EOF marks with no data between them.  There used to be old systems which typically wrote
     three EOF's between tape files.  The tcopy utility will erroneously stop copying early in this case.

     When using the copy/verify option -c, tcopy does not rewind the tapes prior to start.  A rewind is performed after writing, prior to the ver-
     ification stage.  If one does not start at the beginning-of-tape (BOT) then the comparison may not be of the intended data.
