Continue Processing after a signal is caught

Shell Programming and Scripting
1

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

2

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

3

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 ?

#!/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
