Here is a simple example:
address@hidden ~]# echo 4 | awk '/[0-9]/'
4
address@hidden ~]# echo 4 | awk '/[0-9]{1}/'
address@hidden ~]# echo 4 | awk '/[0-9]{1,1}/'
address@hidden ~]# echo 4 | awk '/[0-9]{1,8}/'
address@hidden ~]# echo 4 | awk '/[0-9]{1,}/'
address@hidden ~]# echo 4 | sed -r '/[0-9]/!d'
4
address@hidden ~]# echo 4 | sed -r '/[0-9]{1}/!d'
4
address@hidden ~]# echo 4 | sed -r '/[0-9]{1,}/!d'
4
address@hidden ~]# echo 4 | sed -r '/[0-9]{1,7}/!d'
4

address@hidden ~]# uname -a
Linux d20c 2.6.32.9-70.fc12.i686.PAE #1 SMP Wed Mar 3 04:57:21 UTC 2010 i686

address@hidden ~]# rpm -q gawk

I'm using Fedora 12, up to date as of an hour ago.
