Sed is a stream editor for filtering and transforming text. this cheatsheet covers common editing tasks, addressing, substitutions, and in place edits. general command forms. common cli flags. replace text with s old new . apply commands to specific lines. control output and remove lines. add or replace whole lines. It works with gnu sed because sed will typically have read a buffer full of data from file (4k in my case) before overwriting it with the i command. that wouldn't work if the file was more than 4k except for the fact that sed also buffers its output. The second option for gnu sed (the default version of sed on most linux distros), you can use the i option to edit the file directly in place. this avoids the need for redirection and overwriting files. In the examples presented so far, the output from sed was displayed on the terminal or redirected to another file. this chapter will discuss how to write back the changes to the input files using the i command line option.
