This has nothing to do with *nix: it's the number of chars raised to the power of count of positions: 26 ^ 4 = 456976. Given your specification will not change again, e.g. duplicates allowed in the string, permutations allowed, etc.

If you do only printing...and have enough memory...
Code:
printf "%s\n" {a..z}{a..z}{a..z}{a..z}

Code:
printf "%s\n" {a..z}{a..z}{a..z}{a..z} | wc -l
