while [[ "$environment" == "dev" ]];   curl command  done 

you can write separate function below , use:

#!/bin/sh  count=0 execute_curl () {    count=`expr $count + 1`    curl command    if [ $? -ne 0 ] && [ $count -lt 3 ]          execute_curl    else       return $?    fi }  while [[ "$environment" == "dev" ]]; execute_curl done
