Every possible combination of given letters - BASH

If you want to create every possible word or combination of letters (or any other characters) you can use very simple BASH function:

$ echo {a..c}

This command will print all possible letters starting with a and ending on c (inclusive), so the result is:

a b c

You can get every possible combination of letters from the given range, which length is larger than 1, i.e.:

$ echo {a..c}{a..c}

This command will print every possible combination of letters starting with a and ending on c (inclusive) with another letter from the same range. The result result is:

aa ab ac ba bb bc ca cb cc
