Using echo effectively creates a "new" file with new permissions.
My preference is to use "tail" to tail the file over itself.
I.E.
#tail oldfile > oldfile
This preserves all existing permissions and ownerships.

Subject: RE: [newbie] deleting contents of a file
Dan,
Many people suggested removing the file and then recreating a new empty
file. While not difficult, that does take a little more time. Your
method is much simpler and very quick. I just tried it on a log file and
it works great.
Can anyone give me a reason why this method might cause problems?
Thanks

Echo an empty string into it:
$ echo '' > filename.txt
That '' is a pair of single-quotes, incidentally. It's sort of hard to
see that in some fonts...
