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!

services

services(4)							   File Formats 						       services(4)

NAME

       services - Internet services and aliases

SYNOPSIS

       /etc/inet/services

       /etc/services

DESCRIPTION

       The services file  is a local source of information regarding each service available through the Internet. The services file can be used in
       conjunction with or instead of other services sources, including the NIS maps "services.byname" and the NIS+  table  "services."   Programs
       use the getservbyname(3SOCKET) routines to access this information.

       The services file contains an entry for each service. Each entry has the form:

	 service-name	port/protocol	aliases

       service-name	This is the official Internet service name.

       port/protocol	This field is composed of the port number and protocol through which the service is provided, for instance, 512/tcp.

       aliases		This is a list of alternate names by which the service might be requested.

       Fields  can  be separated by any number of SPACE and/or TAB characters. A number sign (#) indicates the beginning of a comment; any charac-
       ters that follow the comment character up to the end of the line are not interpreted by routines which search the file.

       Service names may contain any printable character other than a field delimiter, a NEWLINE, or a comment character.

       Any changes to a port assignment do not affect the actual port registration of the service.

FILES

       /etc/nsswitch.conf    configuration file for name-service switch

SEE ALSO

       getservbyname(3SOCKET), inetd.conf(4), nsswitch.conf(4)

NOTES

       /etc/inet/services is the official SVR4 name of the services file.  The symbolic link /etc/services exists for BSD compatibility.
