SED - sed is a stream editor. The major use of stream editor is to perform basic text transformations on an input stream (a file or input from a pipeline). While in some ways similar to an editor which permits scripted edits (such as ed), sed works by making only one pass over the input(s), and is consequently more efficient. But it is sed’s ability to filter text in a pipeline which particularly distinguishes it from other types of editors[1]. it basically means that all the editing are made by calling the command and sed will execute the directions automatically. sed is a very powerful and fast way to transform text.
