Ok guys the output is almost there!
My Code:
-----------------------------------------------------------------------
find / -type f -name '.bashrc' -print -exec grep PS1 '{}' \; 2>/dev/null | xargs ls -l
-----------------------------------------------------------------------
tells bash:
find all files with the name .bashrc on the system and print that. Execute the grep command that mattches any pattern that is relevent to the PS1. Redirect all error ( Permission denied ) to a null folder and pipe everthing to the xargs and display the security.
Starting with the -exec is where i get confused.
As for the output, im getting a lot of " PS1: no file or directory " errors. I dont like that and have no clue how to fix this.

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 "
