history — display command history
SYNOPSIS
history [–nr][first [last]]
DESCRIPTION
history displays 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 shell stores your command history in the file given by the variable
HISTFILE ;by
default, .sh_history. The variable
HISTSIZE gives the number of commands kept in the
file; if HISTSIZE is not defined, the default is 128.
