Check for errors when running a command through multiple pipes
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 IOMultiPipe;
my $pipes = IOMultiPipe->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';
