HOSTNAME

[tom quach_1]

Dear,

man hostname shown that /sbin/init.d/hostname
would set the hostname parameter on hpux 11.31
but when i do echo $ HOSTNAME
i get this error,
sh: HOSTNAME: Parameter not set
then i have to set hostname in /etc/profile
to get hostname from echo command.
does anyone know why.
Thanks in advance.
Tom

HOSTNAME is just a shell variable.

If you wish it set for everyone's shell then you put it in /etc/profile.

e.g.

export HOSTNAME=`hostname`

Hi Tom:

The 'HOSTNAME' variable is defined and editted in '/etc/rc.config.d/netconf'. It is established in '/sbin/init.d/hostname'.

If you want to use it in a script, reference it as:

# echo $(hostname)

Or:

# ME=$(hostname); echo "I am at '${ME}'"

Regards!

In the /sbin/init.d/hostname script, you won't see HOSTNAME= anywhere in the script. It is set in the startup script configuration file located in /etc/rc.config.d/netconf. However, this variable is only used during startup.

If you really need HOSTNAME set, do it in /etc/profile:

export HOSTNAME=$(hostname)

check you have hostname

#hostname

if not set then run the command
#set_parms host_name


otherwise follow the instruction listed above.
