You can probably do it with ls, but I like du (man du). For example
fileToTest=/home/you/growingfile
fileSize=`du -ms $fileToTest | cut -f 1` # discarding file name from
# output
if [ $fileSize -gt 10 ] ;
then
do something
fi
I wrote a script a while back when I was just starting with bash that
might do what you're looking for (but I'd now use cut instead of calling
awk!): http://clevername.homeip.net/sizetest
