    see Re: Perldoc Keyword Search (update4)

    > pd x Matches for x found in : /usr/share/perl/5.10/pod/perlop.pod

    pager are opened for each match and files are scolled to the right place with highlighted keyword

    ">>> X<x> <<<" in perlop Binary "x" is the repetition operator. In scalar context or if + the left operand is not enclosed in parentheses, it returns a strin +g consisting of the left operand repeated the number of times spe +cified by the right operand. In list context, if the left operand is +enclosed in parentheses or is a list formed by "qw/STRING/", it repeats +the list. If the right operand is zero or negative, it returns an +empty string or an empty list, depending on the context. print '-' x 80; # print row of dashes print "\t" x ($tab/8), ' ' x ($tab%8); # tab over @ones = (1) x 80; # a list of 80 1's @ones = (5) x @ones; # set all elements to 5

    HTH! =)

    Another approach: type "x" in the search-field here: http://perldoc.perl.org and you'll get

    • x
    • xor
    These operators are documented in perlop
