Note that this is a job for cut(1):
$ cut -d" " -f1 input
Interestingly, the fastest way to do that job is to use
a regular expression with Python. This is about twice
as fast as the proposed perl solution:
$ python -c 'import re; print re.sub(" .*\n", "\n", file("input").read())'
(Of course, in a script you would write that command in
a more readable way instead of trying to squeeze it all
on a single line.)
Best regards

PS: Of course, if you really need the last percent of
speed, then you should write your own specialized tool
in C.
