fi is used in scripts to end a if statement afaik so it will execute the rest of a script.

'fi' is simply the sh-style name for 'endif', to finish an 'if' statement. E.g.:
Code:
#!/bin/sh # Check if this file exists: if test -e config.file then echo "You have a config.file file" else echo "No such file config.file" fi echo "Finished with my 'if' test"

GeraldKo (and anyone else who wondered...) --
regarding the esac reference above: it performs the same function at the conclusion of a case statement.

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.

There's elif, too:
Yeah, it could be done with else and if, but then you'd have to go fi-fi-fi-fi at the end...
Code:
if ... ; then ... elif ... ; then ... elif ... ; then ... elif ... ; then ... else ... fi
Thanks.
