Repeat-By:

        I am using history -s inside a script to add new commands to 
        history and I call that script as below

        prompt> source ~/bin/commandbrowser.sh 
                or
        prompt> . ~/bin/commandbrowser.sh 

        and the commandbrowser.sh script looks somewhat like this

----------- S C R I P T ----------
        CMD="echo jeeva"
        history -s $CMD
        $CMD
