Daniel mentioned checking the man page for hostname.
It's too long to include everything, but here is the
-s part:
-s, --short
Display the short host name. This is the host name
cut at the first dot.
so here is the part from my /etc/hosts file:
# Do not remove the following line, or various
programs
# that require network functionality will fail.
...
127.0.0.1 localhost.localdomain localhost
Linux
...
so here is different outputs from hostname:
[EMAIL PROTECTED] kdtop]$ hostname
Linux
[EMAIL PROTECTED] kdtop]$ hostname -s
localhost
[EMAIL PROTECTED] kdtop]$
