I've usually used
$ cp /dev/null /path/to/filename

but just might start using
$ : > /path/to/filename

hadn't thought of that before -- never liked redirection as the first
character of a command. On a mac, the cp takes way longer to run
ubik:~ jolomo$ time : > /var/tmp/00

real    0m0.000s
user    0m0.000s
sys     0m0.000s
ubik:~ jolomo$ time cp /dev/null /var/tmp/01

real    0m0.005s
user    0m0.001s
sys     0m0.004s


And I'm in a hurry!!
