$SHORT_DOC fc [-e ename] [-nlr] [first] [last] or fc -s [pat=rep] [cmd]
fc is used to list or edit and re-execute commands from the history list.
FIRST and LAST can be numbers specifying the range, or FIRST can be a
string, which means the most recent command beginning with that
string.
-e ENAME selects which editor to use. Default is FCEDIT, then EDITOR,
then the editor which corresponds to the current readline editing
mode, then vi.
then vi.
-l means list lines instead of editing.
-n means no line numbers listed.
