( #3333=superdoc: print w/replies, xml ) Need Help??
Hi fellows, i would like to point out the different behavior of glob utilized in scalar context when the key is a variable or a literal.
WRONG my @sign_arr=('A1' .. 'A9'); for my $sign (@sign_arr) { my $filename = <*$sign*.pkl>; print "$filename\n" if defined($filename); } # OUTPUT: # file_A1_.pkl # file_A3_.pkl # file_A5_.pkl # file_A7_.pkl # file_A9_.pkl # RIGHT my $filename; $filename = <*A1*.pkl>; print "$filename\n" if defined($filename); $filename = <*A2*.pkl>; print "$filename\n" if defined($filename); $filename = <*A3*.pkl>; print "$filename\n" if defined($filename); $filename = <*A4*.pkl>; print "$filename\n" if defined($filename); $filename = <*A5*.pkl>; print "$filename\n" if defined($filename); $filename = <*A6*.pkl>; print "$filename\n" if defined($filename); $filename = <*A7*.pkl>; print "$filename\n" if defined($filename); $filename = <*A8*.pkl>; print "$filename\n" if defined($filename); $filename = <*A9*.pkl>; print "$filename\n" if defined($filename); # OUTPUT: # file_A1_.pkl # file_A2_.pkl # file_A3_.pkl # file_A4_.pkl # file_A5_.pkl # file_A6_.pkl # file_A7_.pkl # file_A8_.pkl # file_A9_.pkl
A bug?

to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or or How to display code and escape characters are good places to start.
