This shell script generates a randomized string from a given alphabet. The script takes an alphabet, count and length parameters as input. The strings are generated according to the following rules:

The string shall have a length no more than the specified length.

There may be any number of character substrings. However at no time the length of such a substring may exceed the count. So the count 4 and with alphabet a, b we may have any number of character strings like a, aa, aaa, b, bb, bbb appearing anywhere in the final string.

There are 2 random number generators. The first one determines the character to be repeated and the second one determines the number of times it repeated.
