\section random random - generate random number

\subsection random-synopsis Synopsis
|
|
<tt>random [SEED]</tt>
|

|
|
\subsection random-description Description
|
|
|
|
\c random outputs a random number from 0 to 32766, inclusive.
|
|
|
|
If a \c SEED value is provided, it is used to seed the random number
|
|
generator, and no output will be produced. This can be useful for debugging
|
|
purposes, where it can be desirable to get the same random number sequence
|
|
multiple times. If the random number generator is called without first
|
|
seeding it, the current time will be used as the seed.
|
|
|
|
\subsection random-example Example
|
|
|
|
The following code will count down from a random number to 1:
|
|
|
|
<pre>
|
|
for i in (seq (random) -1 1)
|
|
echo $i
|
|
sleep
|
|
end
|
|
</pre>
