I understand. :-)
My point is that this list is Ubuntu specific & the OP was having issues
with specific command line instructions. While the dot command does
indeed work, the man page on this system shows _only_ `:' so that's what
_I'd_ recommend when providing Ubuntu specific advise.
Further, I also see that the reason for changing from dot to colon is to
avoid issues with the dot in user/group names; seems reasonable to me as
the OP could have had a user/group name of 'vafa.vafa/vafa.mycomputer'
and I wonder if the dot command would have worked in that case. Example:
sudo chown -R vafa.vafa.vafa.mycomputer /MyDirectory
But I just tested and answered my own question as vafa.vafa (or
test.test in my case) doesn't work on Ubuntu when adding a new user; it
gives a warning with "User name has invalid characters" so it's probably
a mute point w/regard to Ubuntu. So I bow to the 'old scripter's' :-) &
thanks for the pointer (pun intended :-).
