Re: [Fail2ban-users] datepattern regex for listserv

[Steve N. <sr...@co...>]

The line breaks you found (or perhaps created) are spurious artifacts.  
The backslashes that you added at the ends of the broken lines fix the 
spurious-linebreaks problem by telling your shell (bash?) to ignore them.

Another way around the problem is to remove the spurious line breaks so 
they don't confuse your shell.  Of course, that would make the command 
line very long indeed, but it *is* a very long line, regardless of 
whether you escape some inserted line breaks.
