Perl expression help...
Pls. advise what is the meaning of below expression...
if ($filename =~ /x([a-zA-Z0-9_\.]+), [0-9]+ bytes/)
--with the 1st enclosed parenthesis...
/x([a-zA-Z0-9_\.]+)
this will match/filter all the filenames with any character, number, or underscore, and /x modifiers means I can put whitespace characters (like spaces, tabs, and newlines) into the expression. ??
-- but not sure with this [0-9]+ bytes/
many thanks...
