Thank you everyone for all your repsonses and I apologize for the simplicity of this question. Here's some of the responses: grep "G\.[0-9][0-9]*" filename egrep -e 'G\.[0-9]' grep "G\.[0-9][0-9][0-9][0-9][0-9]" egrep usually has a better RE collection but: awk '/G\.[0-9]{5} {print}' perl -ne 'print if /G\.\d{5}/' Thanks again everyone.
