Variable Question

Hunki — Mon, 19 Feb 2007 16:29:15 GMT

Is this a correct variable inside a .profile for a user :

export HostName=`/usr/ucb/hostname`

OR whether it should be

HostName=`/usr/ucb/hostname`

thanks,

Hi:

Well, for HP-UX if you want to capture the server hostname and provide it to processes started after login, you would place this in the users '.profile':

# export HostName=`/usr/bin/hostname`

(or, using the preferred POSIX form)

# export HostName=$(/usr/bin/hostname)

Regards!

/usr/ucb/hostname is for the Berkeley version of the hostname command. You should use either /bin/hostname or /usr/bin/hostname utils.

I use the export so the variable will be inherent to child shells. But that is totally up to you.

hi,

It is always better to export a variable if it is used very frequently and also if its value doesn't change very frequently.
also it should be user specific and hence it is appropriate to include this in the .profile file for a user.

Hi Hunki,
if you want to have the full name of teh host:

export HstNam=$(hostname|nslookup|awk '/^Name:/ {print $2}')

bosth hostname and nslookup are in /usr/bin, but I think you don't need to sue teh fullpath, usially /usr/bin is included in default path.

HTH,
Art

Hi Hunki,
We normally export such things which we used regularly. Hostname is common one.

option is :

# export HostName=$(/usr/bin/hostname)
