Advanced sed: Hold Space for Negation
In this episode, Daniel and Justin demonstrate and explain sed's "Hold Space" and command negation features. They start by looking at the Hold Space and its commands for record manipulation in conjunction with the Pattern Space. Then they jump into command negation which helps in times that you DON'T need a command to execute.
