I want to capture the output of a program that prints on STDOUT. I could redirect STDOUT to a file like this:
# See the Cookbook p.263 for redirecting standard output. # Copy the STDOUT file descriptors: my $buffer_file = '/path/to/buffer.txt'; open(OLDOUT, ">&STDOUT"); open(STDOUT, "> $buffer_file") or die "Couldn't redirect STDOUT to $bu +ffer_file: $!"; # Call the script whose output I want to capture: do("/path/to/cgi/mhandler.cgi"); # Close the redirected STDOUT and restore the original: close(STDOUT) or die "Couldn't close redirected STDOUT: $!"; open(STDOUT, ">&OLDOUT") or die "Couldn't restore STDOUT: $!"; close(OLDOUT) or die "Couldn't close OLDOUT: $!";
But it would be more useful if I could capture the STDOUT directly into a $buffer variable instead of a file.
Is it possible to open a filehandle into a variable like that?
