Line-by-line userlist creation

I'm trying to build a line-by-line userlist of random characters. Below I will explain what I wanna do.

aaaa
aaab
aaac
aaad

I want a script that can create all posibilities until xxxx (4-digits).

Is there a way that I can do this via a bash script?

My OS is CentOS 7.0

You can use 

echo {a..z}{a..z}{a..z}{a..z}

You can also use loop for getting the output in the format you desire by using following loop

for i in `echo {a..z}`; do for j in `echo {a..z}`;do for k in `echo {a..z}`; do for l in `echo {a..z}`;do echo $i$j$k$l;done; done ;done; done

The second one is the bad way to do it..
