The long way is:
function select_or_start_ffx
wmctrl -a "Firefox"
if test $status -eq 0
firefox
end
end
You need to use the `test` builtin so that `if` has something to check
the return value of. Alternatively, you can shorten it to:
function select_or_start_ffx
if wmctrl -a "Firefox"
firefox
end
end
Hope that helps. I think you might be getting mixed up with the return
values from wmctrl - it returns 1 if the window doesn't exist, so try
changing the test to `-ne 0` or `if not wmctrl...` respectively.
