<title>The hi Command</title>
<h1>hi</h1>

<!--INDEX "hi command" "command history" -->

The hi command lists the command history.<p>

</dl><h2>Format</h2><dl><dd>

The format for the hi command is:<p>

<pre>
hi [cnt]
</pre>

where:<p>

<table><tr><td>
cnt	</td><td>is the number of commands to list.
</td></tr></table><p>

Entering the command with no parameters lists the last 200 executed com-
mand lines to the screen.<p>

</dl><h2>Functional Description</h2><dl><dd>

The hi command shows the command history, together with the history 
number for each command, in reverse order (the last command entered is 
listed first; the first command entered is listed last). The command num-
bers are reset to zero each time the system is reset.<p>

Entering the hi command with no arguments lists the last 200 commands. 
This option is useful for determining the history number for a particular 
command.<p>

The user can page through the output of the hi command, one screen at a 
time.<p>

The optional cnt parameter selects a set number of lines to be output.
The history list is intentionally in the reverse order to that used in
a C shell, so that the latest entry is displayed first. If a command
line is identical to the previous command, it is not added to the
command history.<p>

Examples illustrating the use of the hi command follow.<p>

<pre>
PMON> hi 3	Display the three last commands.
14 hi 3
13 hi 
12 l

PMON> hi	Display the entire history, using more
13 hi	to control the screen output.
12 l
11 to
10 t
9  l 
8  g start main 
7  hi 
6  g
5  ls -a @epc
4  d Pmon+200+0t13*4
