Code:
[node14 init.d]# export service_cmd=/sbin/service
[node14 init.d]# var1=`cd /etc/init.d/; ls *was.init | awk '!/dmgr/ && !/NodeAgent/ && !/interdependentwas/ {print TRS "${service_cmd} "$0 " status"; TRS = " && "}' ORS=""`
[node14 init.d]# echo $var1
${service_cmd} cmserver_was.init status && ${service_cmd} fmserver_was.init status && ${service_cmd} ihs_was.init status && ${service_cmd} intgserver_was.init status && ${service_cmd} itsmserver_was.init status && ${service_cmd} server2_was.init status && ${service_cmd} sysserver_was.init status
[node14 init.d]# $var1
-bash: ${service_cmd}: command not found
[node14 init.d]#Code:
node14 ~]# ${service_cmd} cmserver_was.init status && ${service_cmd} fmserver_was.init status && ${service_cmd} ihs_was.init status && ${service_cmd} intgserver_was.init status && ${service_cmd} itsmserver_was.init status && ${service_cmd} server2_was.init status && ${service_cmd} sysserver_was.init status
