How to change the system prompt and BG of terminal?
Hi all,
I was wondering how to change the PS1 to my liking?
I tried changing it using PS1='my choice'
it worked but the subsequent terminals i open will not have it as the default PS1 ,how do i change it?
also i am running as super user, and i need to exec bash, to get the bash environment...
So whenever i exec bash, i get the
"bash3.2#" system prompt....
How to change it permanently?
Other question is how to change the BG color of the terminal?is there a pkg available that does it or can it be done out of the box?
Again i want this to be permanent so that every time i open terminal i should get the changed BG and not the default one?
PS: am using solaris B-79a
Thanks

env::ps1
Env::PS1(3pm) User Contributed Perl Documentation Env::PS1(3pm)
NAME
Env::PS1 - prompt string formatter
SYNOPSIS
# use the import function
use Env::PS1 qw/$PS1/;
$ENV{PS1} = 'u@h $ ';
print $PS1;
$readline = <STDIN>;
# or tie it yourself
tie $prompt, 'Env::PS1', 'PS1';
# you can also tie a scalar ref
$format = 'u@h$ ';
tie $prompt, 'Env::PS1', $format;
DESCRIPTION
This package supplies variables that are "tied" to environment variables like 'PS1' and 'PS2', if read it takes the contents of the
variable as a format string like the ones bash(1) uses to format the prompt.
It is intended to be used in combination with the various ReadLine packages.
EXPORT
You can request for arbitrary variables to be exported, they will be tied to the environment variables of the same name.
TIE
When you "tie" a variable you can supply one argument which can either be the name of an environement variable or a SCALAR reference. This
argument defaults to 'PS1'.
METHODS
"sprintf($format)"
Returns the formatted string.
Using this method all the time is a lot less efficient then using the tied variable, because the tied variable caches parts of the
format that remain the same anyway.
FORMAT
The format is copied mostly from bash(1) because that's what it is supposed to be compatible with. We made some private extensions which
obviously are not portable.
Note that this is not the prompt format as specified by the posix specification, that would only know "!" for the history number and "!!"
for a literal "!".
Apart from the escape sequences you can also use environment variables in the format string; use $VAR or "${VAR}".
The following escape sequences are recognized:
a The bell character, identical to "
