history -- display KornShell command history

SYNOPSIS

history [-nr] [first [last]]

DESCRIPTION

history displays KornShell commands that you executed previously. These commands make up your command history.

By default, history displays a numbered list of the 16 most recent commands, from earliest to most recent. By specifying values for first and last, you can display a specified range of commands rather than the 16 most recent. For example,

history 1 10

displays commands 1 through 10.

The KornShell stores your command history in the file given by the variable HISTFILE. By default, this is sh_histo (.sh_history on POSIX and UNIX systems). The variable HISTSIZE gives the number of commands kept in the file; if HISTSIZE is not defined, the default is 128.

Options

-n: displays the commands but not the command numbers.
-r: displays commands in reverse order, from most recent to earliest.

history is an alias defined with

alias history='fc -l'

ENVIRONMENT VARIABLES
