See perlop, and likely perlretut and perlre while you're at it. "Seeing things somewhere" is a good start, but you should read up on the documentation what things mean instead of blindly using them.	[reply]

'x' affects how whitespace and '#' behave. 'm' affects how "^" and "$" behave. 's' affects how "." behaves. See perlre for details on the above (since they affect regex patterns) and see perlop for 'g' (since it's affects the substitution operator).	[reply]
