Hi,
Counting lines inside a file and counting lines inside a file on tape are two different thing.
First of all, if you have a plain text-file you can do this using "wc -l"
F.E. : cat /var/adm/messages | wc -l >>/tmp/lines
This will count the number of lines from de messages file and <strong>appends</strong> this number to the file /tmp/lines
looking on tape depends on how you saved it. "tar tvf /dev/rtp", might tell you the files that are on the tape, but no garantuee. fining out the number of lines per file can only be done when restoring the file. At least for as far as I know. Maybe we can help a little more on this if we get to know the backup tool and method.

DIFF3(1) GNU Tools DIFF3(1)
NAME
diff3 - find differences between three files
SYNOPSIS
diff3 [options] mine older yours
DESCRIPTION
The diff3 command compares three files and outputs descriptions of their differences.
The files to compare are mine, older, and yours. At most one of these three file names may be -, which tells diff3 to read the standard
input for that file.
Options
Below is a summary of all of the options that GNU diff3 accepts. Multiple single letter options (unless they take an argument) can be com-
bined into a single command line argument.
-a Treat all files as text and compare them line-by-line, even if they do not appear to be text.
-A Incorporate all changes from older to yours into mine, surrounding all conflicts with bracket lines.
-B Old behavior of -A. Shows non-conflicts.
-e Generate an ed script that incorporates all the changes from older to yours into mine.
-E Like -e, except bracket lines from overlapping changes' first and third files. With -e, an overlapping change looks like this:
<<<<<<< mine
lines from mine
=======
lines from yours
>>>>>>> yours
--ed Generate an ed script that incorporates all the changes from older to yours into mine.
--easy-only
Like -e, except output only the nonoverlapping changes.
-i Generate w and q commands at the end of the ed script for System V compatibility. This option must be combined with one of the
-AeExX3 options, and may not be combined with -m.
--initial-tab
Output a tab rather than two spaces before the text of a line in normal format. This causes the alignment of tabs in the line to
look normal.
-L label
--label=label
Use the label label for the brackets output by the -A, -E and -X options. This option may be given up to three times, one for each
input file. The default labels are the names of the input files. Thus diff3 -L X -L Y -L Z -m A B C acts like diff3 -m A B C ,
except that the output looks like it came from files named X, Y and Z rather than from files named A, B and C.
-m
--merge
Apply the edit script to the first file and send the result to standard output. Unlike piping the output from diff3 to ed, this
works even for binary files and incomplete lines. -A is assumed if no edit script option is specified.
--overlap-only
Like -e, except output only the overlapping changes.
--show-all
Incorporate all unmerged changes from older to yours into mine, surrounding all overlapping changes with bracket lines.
--show-overlap
Like -e, except bracket lines from overlapping changes' first and third files.
-T Output a tab rather than two spaces before the text of a line in normal format. This causes the alignment of tabs in the line to
look normal.
--text Treat all files as text and compare them line-by-line, even if they do not appear to be text.
-v
--version
Output the version number of diff3.
-x Like -e, except output only the overlapping changes.
-X Like -E, except output only the overlapping changes. In other words, like -x, except bracket changes as in -E.
-3 Like -e, except output only the nonoverlapping changes.
SEE ALSO
cmp(1), comm(1), diff(1), ed(1), patch(1), sdiff(1).
DIAGNOSTICS
An exit status of 0 means diff3 was successful, 1 means some conflicts were found, and 2 means trouble.
