It is often useful to chain multiple sed commands and sometimes shuffle them around. In those cases I would need to keep changing the fist sed. Sometimes I need to grep before I sed. Using cat, tail and head makes things more modular in the long run I feel. It’s the ethos of each command doing one small thing
