To get only the "10" from that kind of line into a variable (and it doesn't matter how long this number will become because we only fetch the last field):

With awk:
Code:
VAR=`awk '/^Last Changed Rev:/ {print $NF}' nameofoutputfile`

With sed:
Code:
VAR=`sed 's/^Last Changed Rev: *\([^ ]*\)$/\1/g' nameofoutputfile`


To cut off the header let's use awk again. Let's say the data you want starts at line number 3:
Code:
cat nameofoutputfile | awk 'NR > 2 {print}'

grep-excuses

GREP-EXCUSES(1)                                               General Commands Manual                                              GREP-EXCUSES(1)

NAME

       grep-excuses - search the testing excuses files for a specific maintainer

SYNOPSIS

       grep-excuses [options] [maintainer|package]

DESCRIPTION

       grep-excuses  downloads  the  update_excuses.html file and greps it for the specified maintainer name.  The libwww-perl package is required
       for this script.  If no name is given on the command line, first the environment variable DEBFULLNAME is used if it is defined, and failing
       that, the configuration variable described below is used.

OPTIONS

       --no-conf, --noconf
              Do not read any configuration files.  This can only be used as the first option given on the command-line.

       --wipnity, -w
              Get information from <http://release.debian.org/migration/>.  A package name must be given when using this option.

       --help Show a brief usage message.

       --version
              Show version and copyright information.

CONFIGURATION VARIABLES

       The  two configuration files /etc/devscripts.conf and ~/.devscripts are sourced in that order to set configuration variables.  Command line
       options can be used to override configuration file settings.  Environment variable settings are ignored for this  purpose.   The  currently
       recognised variable is:

       GREP_EXCUSES_MAINTAINER
              The default maintainer, email or package to grep for if none is specified on the command line.

SEE ALSO

       devscripts.conf(5).
