    fc - Display or execute commands from the history list.



    fc [-e ename] [-lnr] [first] [last] or fc -s [pat=rep] [command]



    Display or execute commands from the history list.


    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




      -e ENAME  select which editor to use.  Default is FCEDIT, then EDITOR,

                then vi

      -l        list lines instead of editing

      -n        omit line numbers when listing

      -r        reverse the order of the lines (newest listed first)


    With the `fc -s [pat=rep ...] [command]' format, COMMAND is

    re-executed after the substitution OLD=NEW is performed.


    A useful alias to use with this is r='fc -s', so that typing `r cc'

    runs the last command beginning with `cc' and typing `r' re-executes

    the last command.

    Returns success or status of executed command; non-zero if an error occurs.
