Hi all,

I was unable to set PS1 environment variable (prompt) to a customised one when I logged into an AIX box with normal user credentials and then switched over to the root user credentials via a perl script
which uses Net::Telnet (CPAN) module. Sourcing the script and changing the .profile file solutions provided on the net was not helpful as I was not allowed to do any modifications with respect to settings on the box. So, I found a way where I could accomplish this.

My Solution: While switching over to other user (say root) which is accomplished through su command, we can send required flags and as well the command to be exceuted. So, I could do it in the following manner:

su - root -ip -a -c env;PS1='customized
one';PS1;

where:
-ip: interactive and privileged
-a: export all the subsequent parameters (here it is PS1)
-c: run the command specified as a string following it

Hope this solution could help any one who would encounter similar kind of a problem in the near future.

Regards,
