If your sed version doesn't support the POSIX Character Classes you can use a space and a \t within the square brackets:

Code:
sed 's/[ \t]*$//'

Older versions of sed even doesn't recognize the \t as a tab. In that case you can type <Ctrl-V> <TAB> successively instead of \t:

Code:
sed 's/[     ]*$//'

Regards
