Help with script logic.

Hello everyone, I'me new to shell scripting and have been trying to create a custom script to do the following steps -

1. search for the word servicedown within all log files in a specific directory
2. After finding the keyword servicedown, grab latest timestamp from that log
3. Set variable with results from #2
4. loop previous log files and grab the timestamp from the last line from next newest log in that directory.
5. Set a variable with the results from #4
5. Calculate difference between the 2 timestamps in minutes.

Here is what I have so far, and it's very incomplete. I've been trying to piece this script together as best as I can and could really use any help I can get.

Code:

#!/sw/bin/bash


LogFile="abc.server-ny-abc01.200908270000+0000.log"

LogFile2="$(ls -lt /abc01/ihost/log/abc*log|/sw/bin/grep -v abc.log|/sw/bin/grep -A 1 $LogFile| /sw/bin/tail -n 1| /sw/bin/sed -n "s/.*\(abc\..*\)/\1/p")"

/sw/bin/tail -n 1 /abc01/imail/log/$LogFile2 | /sw/bin/awk '{print "Crash Start",substr($0,1, 13)}'
/sw/bin/grep -i "servicedown" /abc01/ihostlog/abc.log | /sw/bin/awk '{print "Crash End",substr($0,1, 13)}'

exit 0

Here is the current format of the logfiles being generated.-
abc.server-ny-abc01.200908270000+0000.log

NAME

       shells - shell database

SYNOPSIS

       /etc/shells

DESCRIPTION

       The shells file contains a list of the shells on the system. Applications use this file to determine whether a shell is valid. See getuser-
       shell(3C). For each shell a single line should be present, consisting of the shell's path, relative to root.

       A hash mark (#) indicates the beginning of a comment; subsequent characters up to the end of the line are not interpreted by  the  routines
       which search the file. Blank lines are also ignored.

       The following default shells are used by utilities: /bin/bash, /bin/csh, /bin/jsh, /bin/ksh, /bin/ksh93, /bin/pfcsh, /bin/pfksh, /bin/pfsh,
       /bin/sh, /bin/tcsh, /bin/zsh, /sbin/jsh, /sbin/sh, /usr/bin/bash, /usr/bin/csh, /usr/bin/jsh, /usr/bin/ksh, /usr/bin/ksh93, /usr/bin/pfcsh,
       /usr/bin/pfksh, /usr/bin/pfsh, and /usr/bin/sh, /usr/bin/tcsh, /usr/bin/zsh, and /usr/sfw/bin/zsh. /etc/shells overrides the default list.

       Invalid shells in /etc/shells could cause unexpected behavior, such as being unable to log in by way of ftp(1).
