If you ever have a situation where you have a huge file and want to extract a certain portion from this file (e.g. a log file or database dump), you can use the sed command.

Sed is a stream editor that is used to perform basic text transformations on a file or input stream.

👇

Extract between two patterns (or words):

sed -n '/beginning_pattern/,/end_pattern/p'

Extract from a pattern (word) to the end of the file:

sed -n '/beginning_pattern/,$p'
