I'm digging the idea of your command. Along the same lines I've got
this awk snippet that I made and then forgot about. It functions like
the cisco pipe begin/end commands:
#!/bin/sh
if [ "x${2}" = "x" ]; then
awk "/${1}/{temp=1}; temp==1{print}"
else
awk "/${1}/{temp=1};/${2}/{temp=0}; temp==1{print}"
fi
Usage:
cat router-confg | begin_regex 'line vty' '!'
If you omit the second argument it just shows you from your match until
the end of file.
