Hi Fellas,

Need your help in while loop, well I have endless while loop and accepting a resp from user and I need to jump out of the loop if I pass certain string and should not pass to next condition.

while :
do
echo "Enter Event :"
if [ -z "$resp" ] || [ $resp -eq "mailsend" ];then
echo "No Event number provided, exiting now"
mailsend ----------------> This is an another function that should get executed.
exit
else
ANSWER=`cat $EVENTDIR/$resp.html | grep -A4 "Characteristics and Indicators" | tail -n1 | awk '{print $NF}'`
echo $ANSWER
fi

Please put your code into [CODE] tags for better readability.

First, your loop needs to end with "done". e.g.:
To exit the loop based on some condition, you can use the "break" command.

If you don't have them already, head over to http://tldp.org and get the Bash Guide for Beginners, and the Advanced BASH Scripig Guide (ABS)

break does what it says.

look at select and case in the bash manual.

even better, look at dialog or Xdialog
