It gives you the answer, actually:

[Head|Tail] = [a, b, c, d, e]

Head is the head of the list and Tail is the tail, bound by the
pattern-matching statement. Alternatively, you can use the built-in
functions hd/1 and tl/1, e.g. if I have a list in the variable List,
hd(List) gives the head and tl(List) gives the tail.

2) I like to use Sublimetext as a IDE. But how do I make a programm then

When you have compiled, either manually via erlc or with a build tool, run
"erl" and call the function in the module you want to run. Nothing
IDE-specific there, sorry.
