Normally if a part of a pipe fails, depending on the location, it won't
|
|
be detected. This breaks down a command involving pipes and runs each
|
|
command separately.
|
|
|
|
It uses open3 to run each chunk of the pipe.
|
|
|
|
use IO::MultiPipe;
|
|
|
|
my $pipes = IO::MultiPipe->new();
|
|
|
|
#This sets the pipe that will be run.
|
|
$pipes->set('sed s/-// | sed s/123/abc/ | sed s/ABC/abc/');
|
|
if ($pipes->{error}){
|
|
print "Error!\n";
|
|
}
|
|
|
|
#'123-ABCxyz' through the command set above.
|
|
my $returned=$pipes->run('123-ABCxyz');
