Here's an example to check log as the server starts and look for a WORD to confirm a start of Service. Here's I am looking for word 'RUNNING' in the log every 10 seconds and when found, I am coming out of the loop.

#!/bin/ksh
while [ 1=2 ]; do
grep RUNNING /opt/logs/Server.log>a.txt
if [ -s a.txt ]
then
echo "Found RUNNING"
exit 0
fi
echo 'checking Server.log for status RUNNING every 10 seconds until completed'
sleep 10
done


Hope this helps!

NAME

       FileLog - Traces File Server operations

DESCRIPTION

       The FileLog file records a trace of File Server (fileserver process) operations on the local machine and describes any error conditions it
       encounters.

       If the FileLog file does not already exist in the /var/log/openafs directory when the File Server starts, the server process creates it and
       writes initial start-up messages to it. If there is an existing file, the File Server renames it to FileLog.old, overwriting the existing
       FileLog.old file if it exists.

       The file is in ASCII format. Administrators listed in the /etc/openafs/server/UserList file can use the bos getlog command to display its
       contents. Alternatively, log onto the file server machine and use a text editor or a file display command such as the UNIX cat command. By
       default, the mode bits on the FileLog file grant the required "r" (read) permission to all users.

       The File Server records operations only as it completes them, and cannot recover from failures by reviewing the file. The log contents are
       useful for administrative evaluation of process failures and other problems.
