Re: Bash style of if-then-else?

If you're writing a Bash-specific script then it's preferable to use
double square brackets (see http://mywiki.wooledge.org/BashFAQ/031).

if [[ -f $file ]]
then
    do something
fi

I prefer forms using the fewest number of semicolons, but I really
don't think it matters. Consistency is more important.
