Continue Processing after a signal is caught
Is it possible to continue after signal is caught and control goes to function specified in the trap statement?

You mean "continue from where the script was interrupted"?

Yes. I would like to come back and continue. The basic idea is to retry for three times and then error out.

Hi Soham,

Could this help you ?
Code:
#!/bin/sh

count=0
trap 'CheckSignal' 1 2 15

function CheckSignal
{
  echo "recved signal"
  count=$(($count + 1 ))
  if [ $count -eq 3 ]
  then
      echo "exiting"
      exit
  else
      echo "continue"
  fi

}

while true
do
  echo "Test"
  sleep 10
done
