ed Cheat Sheet

ed is a small, powerful, line-oriented, command-line-interfaced text editor. All editors frustrate, but ed often amazes while others disappoint.

ed, man! !man ed — ed is the standard text editor.

man ed for more information.

Start ed from your shell command line:

ed file

Edit file by entering ed commands with the following syntax:

[range][command]

range specifies the line or block of consecutive lines (syntax: from-line,to-line) to which command is applied. Default range is the current line except where noted below with a parenthesis preceding the command syntax. Lines are specified as follows:
