Hi,

You already got the answer - fi ends an if, much like endif does in other languages (some would say endif would have been better for bash too).

There are four main conditional statements in shell scripts:
if... ; then...; else...; fi
for ...; do...; done
while...; do...; done
and

case ... in
...
esac

You can see that if ends in fi, and case in esac. for and while both use the more understandable do...done convention which is appropriate for loops.
