Delete trailing white space

I have a string "disk0 with a trailing white space after it" but I want to get rid of this white space from right to left so that I am left with "disk0" only.

Using sed 's/ $//g' doesn't seem to work

Any ideas ?

Thanks

using Perl:
Code:
perl -pi -e 's/disk0\s/disk0/' file.txt

edit: if there could be multiple spaces after disk0 are you are interested in truncating them all:
Code:
perl -pi -e 's/disk0\s+/disk0/' file.txt

Try

Code:
sed -e "s/ *\$//g"

if you don't care about preserving spaces between fields
awk '{$1=$1}1' file

methyl, thanks, that seems to have the desired effect.
At least I'm not getting the sed: 1 "s/ \n/g\n": unterminated substitute pattern error

you can also use it

perl -pi -e 's/disk0 */disk0/g' filename
