It looks like you solved this, but I believe this should be (it's been 
awhile since I've done this):

if [ -f wget-log ]
   then rm wget-log
fi

for a one-liner like this, you could just as easily write:

[ -f wget-log ] && rm wget-log

or

test -f wget-log && rm wget-log

NOt sure exactly why you're doing this.  It looks like you're putting wget 
in the background, then waiting around until it finishes.  So why 
background it at all?
