Hi all, 
thanks for your new posts.
I see. Thanks for the info.
I´ve never come into contact with vi so far. I´ve always used nano for editing config files.
But it´s good to know that some sytnax seems to be kind of universal… 
@nevj :
Thanks Neville.
I guess you´re referring to: Best one-liner? - #12 by nevj .
Many greetings to all.
