NAME

random - generate random number

Synopsis

random [SEED]

Description

The random command is used to generate a random number in the interval 0<=N<32767. If an argument is given, it is used to seed the random number generator. 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.

Example

The following code will count down from a random number to 1:
 
 for i in (seq (random) -1 1)
         echo $i
         sleep
 end
 


 

Notre repentir n'est pas tant un regret du mal que nous avons fait,
qu'une crainte de celui qui nous en peut arriver.
