Random Number Variable in BASH - Linux Commands • In this video we go over how to generate random numbers in bash using the random builtin variable. The random variable doesn't act like any normal variable in BASH. Assigning a number to the random variable seeds the variables random number generator instead of storing it. • As the random variable generates pseudorandom numbers, by controlling the seed value you can actually predict the numbers that the random variable will produce. • The first example that we go over is how to produce random numbers that are within a range of 0-10 and 1.10. • We expand on this in the second example by restricting the numbers produced to be a binary random choice of either 0 or 1. • Following on we create a dice roll by restricting the range of random numbers to be 1-6. • In the next example we shift the range to start at 1000 instead of zero or one and restrict the upper limit to 1500. • The final example illustrates a method to create numbers larger than the largest number the random variable is capable of producing which is 32,767. • We generate 6 digit random numbers but the same method can be used to produce much larger numbers. • Subscribe: https://www.youtube.com/user/linuxlee... • Blog: http://www.linuxleech.com • Twitter: / linuxleech • Facebook: / linuxleech • Google+: http://www.gplus.to/linuxleech
