sed is a stream editor used to perform basic text transformations on an input stream (a file or input from a pipeline).

sed takes one or more editing commands and applies all of them, in sequence, to each line of input.

After all the commands have been applied to the first input line, that line is output and a second input line is taken for processing, and the cycle repeats.
