in reply to New File Not Working

ALWAYS CHECK THE RETURN FROM open.

my $infile = qq{PSR_Date.txt}; my $outfile = qq{PSR_OutputDate.txt}; open( my $infh, q{<}, $infile ) or die qq{Can't open '$infile' to read +: $!\n}; open( my $outfh, q{>}, $outfile ) or die qq{Can't open '$outfile' to w +rite: $!\n}; while( defined( my $line = <$infh> ) ) { ## ... print $outfh $line; } close( $infh ); ## Note that depending on OS, amount written, buffering, phase of moon + you might not see output in the file until you do this. close( $outfh );
