Metasploit Revealed: Secrets of the Expert Pentester

The split function

We can split the value of a string into an array of variables using the split function. Let's have look at a quick example that demonstrates this:

    irb(main):001:0> a = "mastering,metasploit"
    => "mastering,metasploit"
    irb(main):002:0> b = a.split(",")
    => ["mastering", "metasploit"]
    irb(main):003:0> b[0]
    => "mastering"
    irb(main):004:0> b[1]
    => "metasploit"

We can see that we have split the value of a string from the "," position into a new array b. The string "mastering,metasploit" now forms 0^th and the 1^st element of the array b, containing the values "mastering" and "metasploit" respectively.
