UNIX for Advanced & Expert Users

My os is sun solaris 8

I have following prompt variable

PS1="`uname -n`$" ; export PS1

this work fine it set the hostname follow by $

but I just installed sudo
and when i issue sudo -s to gain root access
It still set my hostname follow by $
rather than setting hostname follow by #

I tried modifying my .profile so that it includes

UID=`id | awk '{print $1}' | cut -c5`

if [ "$UID" = "0" ]
then
PS1="`uname -n`#" ; export PS1
else
PS1="`uname -n`$" ; export PS1
fi

but this still did not work, when I issue sudo -s
Can you help, Please

Basically, I want to set my prompt variable in my .profile file so that when i sudo -s my PS1 is set
to hostname follow by #

Your .profile is only sourced when you log in. You're not logging in.

Whether or not you can solve this depends on your shell. Look at the docs for your shell and see if you can define a file that gets sourced with new invocation of a shell.

if you are sudo'ing to root... you only need to put the new prompt in root's .profile.

Where are you putting this code? in your user's .profile? that wont work as Perderabo has said b/c you arent logging as yourslef again... you are going to root.

You need to put the new PS coding in /etc/profile for it to affect root when you sudo... /etc/profile if it exists is read everytime anyone logs in, including root user.

i have this in my root .profile

PS1="`uname -n`#" ; export PS1

when i issue su -
I get my root .profile, hostname follow by #

but when I sudo -s i get my user .profile loaded up which has hostname follow by $

Can you help, please. so that when i issue sudo -s
i get hostname follow by #

Thanks
