The history
feature records commands
typed in the Korn shell. In the Korn shell,
history
is automatically
set up when the user first enters the shell. Whenever the user types
in a command, this function records it on a history list. The history
list is stored in the user's home directory in a file named ~/.sh_history.
By default, the Korn shell keeps a record of the last 128 commands entered but
only displays the last 16 commands by default.
| Command Format: |
| history [options] |
Specifying a number preceded by a dash
as an option will display that number of lines. Specifying a number without
a dash will show the history lines from that number to the last
command entered. The Figure shows the listing from the history
command. In the first example,
using the history
command by itself, the last 16 commands are displayed. The second
example displays only the last three commands because the -3 option
was used.
