Re: How to create username with "."

Hi Marq
I am using RHEL v4 and works fine, I can add users with a ".", it happened to
me with RHEL v3 and solved the problem with updating some package
shadow-utils.

Thanks

Hi

When i create username like this
"useradd user.name"
It shows the error message saying that the name contains invalid

It is bad idea to create such users. For example, chown command accepts
argument of type "user.group". You should stick with letters and numbers.

The chown(1) man page says that a colon ":" is the delimiting character:

NAME
chown - change file owner and group

SYNOPSIS
chown [OPTION]... [OWNER][:[GROUP]] FILE...


My advice to Marq would be to use a dummy username, and then manually edit
the passwd and shadow files. We've been using usernames like first.m.last
for several years to maintain compatibility with another operating system;
the users don't like having to use the long usernames but it works.
