Question - is it possible to use the puppet regsubst function in place
of the exec used here (to save spawning a new shell process) ?

Well, functions are ordinary on the compiling side. If you can figure
out what to do when compiling that is preferable.
Alternatively, you can call functions on the agent side by using a
Deferred value that delays the call and makes it on the agent side.
You need Puppet 6 to be able to do that. (And if you need custom logic
you can write your own function in Ruby using the function API).
To answer if there is a better way we need to understand what you are
actually doing (I did not try to make sense of what your exec and the
perl logic actually does...

Nice... I solved my probleman using the:
define replace($file, $pattern, $replacement) {
exec { "/usr/bin/perl -pi -e 's/$pattern/$replacement/' '$file'":
onlyif => "/usr/bin/perl -ne 'BEGIN { \$ret = 1; } \$ret = 0
if /$pattern/ && ! /$replacement/ ; END { exit \$ret; }' '$file'",
}
}
Then i my class used:
replace { "/etc/bashrc":
file => "/etc/bashrc",
pattern => "PS1",
replacement => "PS1 DOMAINA.COM <http://DOMAINA.COM>"
}
Worked perfectly... Know i will see the other options proposed here.
Thank you evry much guys

fwiw, the newest version of my concat module supports symlinking
into a concat file, so if you have a config file that you would
like users to drop settings it and you want them to only do so
in a very specific place in a file you can now achieve that by
building your config file and including a user editable file
right where you want it.
Very nice feature to give users some rights without loosing
control of the file or its structure.
It wouldn't be too hard to extend it to make arbitrary user
supplied .d directories for daemons that dont support those :)
