Grep from A to B

Grepping multiple lines

I use to grep for multiple lines using grep -A as follows

kubectl describe pod <podname> -n <namespace> | grep -A6 Conditions

Conditions:
  Type              Status
  Initialized       True
  Ready             True
  ContainersReady   True
  PodScheduled      True
Volumes:

It returns 10 lines below the matched word “Environment”.

Get Text Between Two Keywords

Sometimes we want to grep for a words between two keywords.

kubectl describe pod <podname> -n <namespace> | sed -n -e '/Conditions/,/Volumes/p'

Conditions:
  Type              Status
  Initialized       True
  Ready             True
  ContainersReady   True
  PodScheduled      True
Volumes:
