You did not indicate what language your script is written in. There are quite a few sites that have information for debugging a Bash script. http://bashdb.sourceforge.net/bashdb-man.html http://www.tldp.org/LDP/abs/html/debugging.html http://www.softpanorama.org/Scripting/Shellorama/bash_debugging.shtml http://tldp.org/LDP/Bash-Beginners-Guide/html/sect_02_03.html There are lots of others. Just Google or Bing for it. -- Jerry FreeBSD.user@seibercom.net Disclaimer: off-list followups get on-list replies or get ignored.
