Hi,

very good idea for Keith's script!

The trick here is: the shell will replace "\\" with "\" - "\" escapes  
the next character

So the process "grep" will have "r\sync" as it`s parameter. Nothing  
special so far.
"grep" itself always uses regular expression for its matching. So it  
looks for "rsync" in the processlist, because the "\" only escapes the  
next character, in this case the "s" - and so greps command line will  
NOT match.


With best regards,
