What does the construct "}{" mean?
From perlrun:
"-p causes Perl to assume the following loop around your program, which makes it iterate over filename arguments somewhat like sed:
LINE: while (<>) { ...# your program goes here } continue { print or die "-p destination: $!\n"; }
"
The closing brace indicates that the while loop is over, and the opening brace starts a new, bare block to which the "continue" is attached.
