I have a script in which i need to capture everything written to STDOUT.
I have managed to redirect output from STDOUT to $varaible.
But I cant switch STDOUT back.
How can I do this.
Originally I did this
my $out = new IO::Scalar \$variable;
my $stdout = select $out;
...
close select $stdout;
However one of the packages I was using now does print STDOUT where it used to just print;
Thanks, however...
I've read it over and over.
It shows you how to store STDOUT in a variable and how to reopen it to a scalar.
But it doesnt show how to reassign STDOUT from the saved variable, so that normal output is resumed.
In my man page, it explains that (summarized):
open $oldout, ">&STDOUT" #opens STDOUT in $oldout variable
open STDOUT, '>', "foo.out" #redirects STDOUT to "foo.out" (write mode)
open STDOUT, ">&", $oldout #redirect STDOUT once more, this time to $oldout, where the original stdout was
#stored in. So this should effectively restore the normal STDOUT.
Have you tried that?
And added some prints to test if all is well?
