Perl pos printf Keywords The print keyword print prints a string or a list of strings and returns true, if successful. The parametre FILEHANDLE may be a scalar variable with a reference to the file handle. This introduces a level indirection for the print. If FILEHANDLE is a variable followed term, it may be misinterpretedby the system as an operator unless a + is added inbetween, or all arguments are put in parentheses. Without the FILEHANDLE, the last selected output handle is used. Without LIST, the function prints $_ to the current output handle. To use FILEHANDLE and use the $_, a real filehandle like FH and not an indirect filehandle like $fh is required. Syntax print FILEHANDLE LIST print FILEHANDLE print LIST print Examples The code $filename = "assign.pl"; print $filename . "\n"; open(my $fh, "<", $filename) or die "cannot open < " . $filename . ": $!"; read $fh, $f, 1024; print $f; close($fh); returns the contents of the file "assign.pl": assign.pl $tmp = "909135790159"; print $tmp . "\n"; $tmp =~ y/13579/24680/; […] print $tmp .
