How about dupping the filehandle: `sub open_logfile { my $filename = shift; open STDOUTBACK, '>&STDOUT' or die "Can't dup STDOUT\n"; open STDOUT, '> ' . $filename or die "can't write to $filename: $!\n +"; }` [download] In this case any attempt to `print "foo\n"` or `print STDOUT "foo\n"` will go to the logfile. Or just use select: `sub open_logfile { my $filename = shift; open FH, '> ' . $filename or die "Can't write to $filename: $!\n"; select FH; }` [download] In the second case `print "foo\n"` will print where you want but `print STDOUT "foo\n"` will still go to the real STDOUT.

This is correct, but it's not the solution to my problem... I'm redirecting to existing filehandles, not opening new files. --isotope http://www.skylab.org/~isotope/	[reply]

check perltie for tying file handles... there's also IO::Handle for that task. -- Casey I am a superhero.	[reply] [d/l]
