Hi Friends,

The below shell script is written by third party to create B2k_session_id.iam trying to execute this script.When i execute below script it is calling some other scripts.How to find which scripts is calling?

. `execom commfunc.com`
echo " $PRESENTATION_MODE "
if [ "$PRESENTATION_MODE" != "WEB_TBA" ]
then
echo "before exe call"
        sh  //        what is this means? 
           can we execute default script in this  method with out script name?       
 else
        echo "This option is not supported in the Web interface."
        echo "Press transmit key to continue."
        tba_line_stdin
fi

Thanks,

It means execute a command called "sh" if found on the current path.
