Check params for number
I have 2 and three params, both I should make sure thay numbers at one single line insted of checking for each one .
Example I wroote the following way.. checking for 2 and three seperately but I shud be able to do it at on statement
Code:
echo $2 | egrep '^[0-9]+$' >/dev/null 2>&1
if [ "$?" -ne "0" ]; then
  echo "Please enter positive integer for offset as well as Stale Offset, Exiting"
  exit 1
fi

Is this what you mean?

Code:
if [ -n "`echo "${2}${3}" | tr -d '0123456789'`" ]
  echo "Please enter positive integer for offset as well as Stale Offset, Exiting"
  exit 1
fi
