Code Shell Programming
Hi,

I am using two files - one file contains list of service name , other file contains commands for each of these service name .

I have to read each service name and check this string in 1.cfg file , if it exists , then i have to read another file (commands file ) and take the string and check if it is in 2.cfg file . i have to continue till end of the line in the files.

Note : it should be one after the another .

I wrote a script which is has below

Code:
for x in `cat service_list
do
grep $x 1.cfg  > /dev/null 2>&1
 if [ $? -eq 0 ]
                  then
echo "$x exits"
echo "Now checking another file"
fi
for y in `cat command_list`
do
grep $y 2.cfg > /dev/null 2>&1

if [ $? -eq 0 ]
                  then
echo "$y exists"
fi
done
done

here the inner for loop executes completly first , checks all commands and then goes to outer for loop . but my requirement is to check service then check command . and it should repeat like check service and then command.

Please help

Thanks

service

service(8)						      System Manager's Manual							service(8)

NAME

       service - run a System V init script

SYNOPSIS

       service SCRIPT COMMAND [OPTIONS]

       service --status-all

       service --help | -h | --version

DESCRIPTION

       service runs a System V init script in as predictable environment as possible, removing most environment variables and with current working
       directory set to /.

       The SCRIPT parameter specifies a System V init script, located in /etc/init.d/SCRIPT.  The  supported  values  of  COMMAND  depend  on  the
       invoked	script,  service  passes  COMMAND and OPTIONS it to the init script unmodified.  All scripts should support at least the start and
       stop commands.  As a special case, if COMMAND is --full-restart, the script is run twice, first with the stop command, then with the  start
       command.

       service --status-all runs all init scripts, in alphabetical order, with the status command.

EXIT CODES

       service calls the init script and returns the status returned by it.

FILES

       /etc/init.d
	      The directory containing System V init scripts.

ENVIRONMENT

       LANG, TERM
	      The only environment variables passed to the init scripts.

SEE ALSO

       /etc/init.d/skeleton,
       update-rc.d(8),
       init(8),
       invoke-rc.d(8).
