Sample data

controller T1 0/0/0
framing esf
linecode b8zs
channel-group 0 timeslots 1-24
!
controller T1 0/0/1
framing esf
linecode b8zs
channel-group 0 timeslots 1-24
!
controller T1 0/1/0
framing esf
linecode b8zs
!
controller T1 0/1/1
framing esf
linecode b8zs


sed -n '/controller T/{ N; / channel/p; }' <filename>

I have the Oreilly short book in hand ... I need another set of eyes. Not sure what Im doing wrong.

I want to output only the controller Tx lines and the channel-group lines. In the case of the above test data set

controller T1 0/0/1
channel-group 0 timeslots 1-24


Thanks

Something like

sed -n '/controller T/p;/channel/p' <filename>

I hope that helps.

Another way:
awk '/controller T/||/ channel/' filename

 

[p5wizard]

egrep '^controller T|^ channel-group ' filename
