Linux bash script color text

 
Recently in a script I am trying to coloured text in one of the script.
I have been tried couple of ways, failed initially and at the end I got solution.
Content of my script color.sh is following:
echo -e "\e[0;32;47m Hello World \e[0m"
After running the script the expected output in Gray background and text is in parrot green colour.
When I ran command sh color.sh output is:
-e \e[0;32;47m Hello World \e[0m
The output here is as not expected, reason I fond is shell wont support the coloured text.

situation where I need to pass some information down to librelp when it comes to termination. Supposedly a very simple thing to do (a single call). ...

Puppet error 400 on server not authorized to call find

While trying to play with puppet I got error saying that “Could not evaluate: Error 400 on SERVER: Not authorized to call find ……”
The reason for this issue is access permissions for puppet clients.
We need to set proper access permissions in “/etc/puppet/fileserver.conf” file.
Lest say if our puppet master hostname is master.example.com and client hostname is client.example.com, we should add following lines in /etc/puppet/fileserver.conf
