What error are you getting?
Which Unix OS?
Which version?
Which Shell?
What command are you typing at the prompt?

Code:
echo " " > filename

Will delete the previous contents of the file but will not delete the contents present in it entirely.

try one of:
Code:
cat /dev/null > file
echo "" > file

If none of these work, you may not have privilege to do this on the file.
