[[ ]] brackets are an extended version with a more "C-like" syntax, supporting all the usual operators as well as things like && for and instead of -a, || instead of -o.

It can also do glob-like string matching:

Code:
[[ "$STRING" == *abcd* ]] && echo "$STRING contains abcd"

Using these features means the code may not work if you try to port your code to a simpler shell.
