Sounds like you want truncate() but I don't know any command line
interfaces to it. tail and head and it's friends will amount to a
copy/replace and replace too..
perl has truncate so maybe this'll help you some... otherwise you might
have to write it in C. Then submit it for inclusion in the text-utils
package. :)
