Hi again!
Is it possible to get filesize using the wget command?

wget -O- http://cuddlewagon.org/somefile.txt | du -b THEFILE

du -b won't work, try wc -c

This isn't the ideal way of doing it, since it requires you to download the entire file. It is better to just get it from the response header. Not entirely sure how you do it in wget, but with curl you can do

curl -sI $url | grep Content-Length | cut -d ' ' -f 2

When running

wget --spider http://cuddlewagon.org/somefile.txt 2>&1 | grep Length

Will give me:

Length: 543 [text/plain]

Can i use awk to grep only numbers? These numbers will grow in so the regular expression must take value from 1 and above.

I solved this by using:

wget --spider http://cuddlewagon.org/somefile.txt 2>&1 | grep Length | awk '{print $2}'

Gives me:

543
