fc (Unix)

fc is a standard program on Unix and Unix-like operating systems that lists, edits and reexecutes commands previously entered to an interactive shell. fc is a builtin command in the Bash and Zsh shells and is an initialism for "fix command". It is particularly helpful for editing complex, multi-line commands. The editor can be specified by setting the EDITOR (changes the default editor) or the FCEDIT environment variable.
