List or edit and re-execute commands from the history list

Explanation

fc is a little known but very useful bash built-in.

• fc -l will list the most recent 16 commands
• fc will open the last command in a text editor defined in the environmental variable FCEDIT or EDITOR or else vi, and re-execute when you exit
• fc 5 9 will open the history entries 5 to 9 in a text editor
• fc -s pat=sub will run the last command after substituting pat with sub in it (does not open editor)
• fc -s pat=sub cc is the same but on the last command starting with cc
• fc -s cc will run the last command starting with cc
