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.

Hi,
I'm using the command: sed -n '$=' $1 on a sh script on AIX.
This script is used to count the number of lines of files.
If the file has no lines at all the command doesn't return nothing.
I need the command to return 0 when the file has no lines at all.
How can I achieve this?

TAPELIST(5) File formats and conventions TAPELIST(5)
NAME
tapelist - The list of Amanda volumes in use
DESCRIPTION
The tapelist file contains the list of tapes in active use. This file is not ordinarily ordinarily edited or examined manually. Its format
may change, or it may be removed altogether, in future versions of Amanda. It contains lines of the form:
YYYYMMDD label flags [BARCODE:barcode] [META:meta] [BLOCKSIZE:blocksize] [#comment]
Where YYYYMMDD is the date the tape was written, label is a label for the tape as written by amlabel and flags is one of "reuse" or
"no-reuse" and tells Amanda whether the tape may be reused. A non-reusable tape will not be overwritten, even if it is older than dumpcycle
dumps. See the reuse options of amadmin(8). The optional barcode is prefixed with 'BARCODE' if the volume have a barcode. The optional meta
label is prefixed with 'META' if the volume is on a meta volume. The optional blocksize is prefixed with 'BLOCKSIZE'. The optional comment
is prefixed with a '#' and continues to the end of the line. Amanda will maintain this comment until the tape is overwritten. Note that
comments are not allowed on blank lines.
The file is sorted such that the most-recently used tape appears on the first line, and the oldest tape appears on the last line.
Amdump and amflush will by default refuse to write to an unlabeled tape, or to a labeled tape that is considered active or marked
"no-reuse". There must be more tapes in active rotation (see the tapecycle option) than there are runs in the backup cycle (see the
dumpcycle option) to prevent overwriting a backup image that would be needed to do a full recovery.
