  Hi Sumatheja,

 I’m guessing you want a script to run only once (did say whether it was
 per user).  You could add your script to the .bashrc file – this way the
 script would run once when the user logs on.  Alternatively run the
 script and export an environment variable – then check it using an if
 statement before you run the script again, eg;

 if [ -n “$script-has-run-envar” ]; then
     <source_script>
     script-has-run-envar=”Yes”
     export $script-has-run-envar 
I think you mean -without the $ char-  ;-)

      export script-has-run-envar

Regards
