Re: chmod + chown
w00t. i was thinking find was more like the find.exe from dos/win32.
i am certainly glad it isnt :). learn something new everyday.
i appreciate the response (and certainly wasnt aware of the nice -d and -f
switches)
for my next trick i will figure out exactly what permissions to set for
what.
i am working on my desktop/fileserver and toying with samba/ftp in trying to
make it as easy to use as possible for other people. i have 3 120 gig
drives mapped to /mnt/hdc1 hde1 and hdf1 respectively.
i have some stuff i want to run by people, but i will save that for a new
thread
