Hi, I am trying to understand fully a perl program with the following lines:
} elsif( /^(\#?\s*(?:pickup|qmgr)\s+)(?:fifo|unix)(\s+.*)/ ) { if( defined $normalize->{$1} ) { next; } else { $normalize->{$1} = 1; } I do understand the first line, but I can not find what the second line is about. As far as can see the tested line in $_, from a file, is all ASCII with lower case characters. At the begin of the perl program the is no "use <something>". -- fr.gr.
