I really like 'fping' for use in shell scripts. See: http://www.fping.com/ and http://fping.sourceforge.net/man/ It can be 'yum installed' from the CentOS RPMforge repo. So in your script you can just do fping -c 10 <dest1> <dest2> ... <destN> I don't understand exactly what 'scripts which launches 10 pings' and 'execution of single shell scripts' means. So don't think I can help with the scripting part...
