Thanks RudiC,

i have written something like below in sed & awk,
Code:
var1=$(ls /etc/init.d/*was.init | sed '/interdependentwas/d;/NodeAgent/d;/dmgr/d;s#/etc/init.d/##g;s#.*#/sbin/service & status#g' | awk 'BEGIN {ORS=" && "} y{print s}{s=$0;y=1}END{ORS="";print s}')
echo $var1

Output is :
Code:
/sbin/service cmserver_was.init status && /sbin/service fmserver_was.init status && /sbin/service ihs_was.init status && /sbin/service intgserver_was.init status && /sbin/service itsmserver_was.init status && /sbin/service server2_was.init status && /sbin/service sysserver_was.init status

execution of the above $var1 executes only
Code:
/sbin/service cmserver_was.init status

, but not all the services status check with logical AND, can you suggest whats going wrong!

$var1 execution output:
Code:
scripts]# $var1
Server - cmserver is running (5330).

while just the copy paste of the $var content execution:
Code:
# /sbin/service cmserver_was.init status && /sbin/service fmserver_was.init status && /sbin/service ihs_was.init status && /sbin/service intgserver_was.init status && /sbin/service itsmserver_was.init status && /sbin/service server2_was.init status && /sbin/service sysserver_was.init status
Server - cmserver is running (5330).
Server - fmserver is running (6977).
Server is running.
Server - intgserver is running (15401).
Server - itsmserver is running (8771).
Server - server2 is running (7679).
Server - sysserver is running (2698).

simpler code is also welcome Smilie

Thanks,
Chandana

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 or systemd unit in as predictable an environment as possible, removing most environment variables and with the current working directory set to /. The SCRIPT parameter specifies a System V init script, located in /etc/init.d/SCRIPT, or the name of a systemd unit. The existence of a systemd unit of the same name as a script in /etc/init.d will cause the unit to take precedence over the init.d script. The supported val- ues of COMMAND depend on the invoked script. service passes COMMAND and OPTIONS to the init script unmodified. For systemd units, start, stop, status, and reload are passed through to their systemctl/initctl equivalents. 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. The status is [ + ] for running services, [ - ] for stopped services and [ ? ] for services without a status command. This option only calls status for sysvinit jobs. 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. /{lib,run,etc}/systemd/system The directories containing systemd units. ENVIRONMENT
LANG, LANGUAGE, LC_CTYPE, LC_NUMERIC, LC_TIME, LC_COLLATE, LC_MONETARY, LC_MESSAGES, LC_PAPER, LC_NAME, LC_ADDRESS, LC_TELEPHONE, LC_MEA- SUREMENT, LC_IDENTIFICATION, LC_ALL, TERM, PATH The only environment variables passed to the init scripts. SEE ALSO
