Re: [DOC] Incomplete explanation about the regex =~ operator

[kevin]

My message was poorly formatted (I lack of experience) and consequently 
you misunderstood it.
The shell operation is unusual when a regular expression appears inside 
a conditional expression. Indeed, neither the Bash man page or the Bash 
Reference Manual indicates that the shell quotes some characters 
internally (Bash FAQ: 
http://git.savannah.gnu.org/cgit/bash.git/tree/doc/FAQ#n1927).
Moreover, the explanation in the Bash FAQ is unclear; it lacks examples 
to know when "an interference" occurred.

Look at the following answer to get an overview of the issue:
