There is no man page for the if command. What you want to look at is
the bash(1) man page, which is a long one.
I am by no means an expert when it comes to bash programming, so I do
stand to be corrected, but from
what I noticed, 2 problems come to mind right away when looking at
your if statement. First, you want to enclose the condition part in
brackets. Second, since file, and number, are shell variables, they should be in all
caps.
So, rewriting your below code snipit with the 2 fixes I mentioned
would look like:
if [ date -r $FILE +%V -lt $NUMBER ]; then
#statements
fi
Hth.
