What Others Think

Incorrect. It will also match invalid IP-look-alike strings.

Plus it takes way to long and is inefficient. Every grep is a new proces. Plus that an IP address cannot start with a '0', because it will then be interpreted as being octal. Better: grep -r '[1-9][0-9]*[.][1-9][0-9]*[.][1-9][0-9]*[.][1-9][0-9]*' /etc/* And then you still have the problem reported by 0xFF
