random - Print out a random number.
random [-dhV] /[expression]/
random is a program that is part of the numeric utilities package. random will print out a random number determined by the expression that you give. The syntax and program is nearly identical to the range program, except that random picks a number at random from the range expression. If no expression is specified, random will print out a random integer between 1 and 100.

Random number from 1 to 10. $ random /1..10/ 7
From 1 to 10 or from 15 to 20. $ random /1..10,15..20/ 16
An even number from 0 to 10 $ random /0..10i2/ 4
An odd number. Notice the starting number in the range. $ random /1..10i2/ 9
A factor of 3 between 99 and 120. $ random /99..120i3/ 111
A decimal number. $ random /1.1..2.5i0.1/ 1.8
A negative random number. $ random /0.0..-2.0i0.3/ -0.8
random is slow when dealing with large ranges to randomly find a number from. This is because it creates a list of all potential numbers before picking one. So it can be memory intensive for large ranges.
