fc

Official Description

Allows the user to fix previously executed commands through command-line editing.

Syntax

fc [-r] [-e editor] [first [last]]
fc -l [-nr] [first [last]]
fc -s [old=new] [command ]

Options

-r reverses the search order.

-e enables you to choose a different editor (the default is ed).

-l lists previous commands.

-n does not display command numbers for previous commands.

-s substitutes new for old in the command (old is the old string to be replaced by the new string).

Oddities

Typically performed using a command-line editor.

The history command is an alias for fc: history='fc -l'.

The r command (recall) is an alias for fc: r='fc -e -'.

Example

 $ fc -l 1412 print $myvar 1413 ksh 1414 print $myvar 1415 exit 1416 print $myvar ...
