Cut last 3 characters of stdin?

How do I cut the last three characters coming in from stdin?

i.e.

echo "testing 1234" |cut -b9

will do it but not when each "fdgdfgfdgdfjhlkhjhg" is used.

p.s.

Is freenode offline? (can't connect)
How can I redirect this imput into wget without writing to a file?

Code:

cat *.wvx |grep http | cut -b12- | cut ???  | wget -stdin??

You could use awk:
echo "testing 1234" | awk '{print substr($_,0,length($_)-3)}'

If you mean you want to pass a url to wget then use backticks:
wget `command to return url here`

Managed to bodge it. Still looking for a better answer though

here's the code for anyone who wants to download .wvx files as .wmv files:

Code:

cat *.wvx |grep http | cut -b12- | sed 's/"/ /g' |awk {'print $1'} > filelist.txt && wget -i filelist.txt

You may be able to plug this into Mozilla so you have the option of downloading straight away rather than streaming one-off
