I want to get both the output and status of a pipe.
Here is a working example:
#!/usr/bin/perl
use strict;
open my $fh, '-|', 'bash -c "echo Hello; exit 1"';
print <$fh>;
close $fh;
my $status = $? >> 8;
print "$status\n";
Fine. It outputs
Hello
1
Now let's try to use autodie:
#!/usr/bin/perl
use strict;
use autodie;
open my $fh, '-|', 'bash -c "echo Hello; exit 1"';
print <$fh>;
close $fh;
my $status = $? >> 8;
print "$status\n";
No good, that breaks it:
Hello
Can't close(GLOB(0x10082a098)) filehandle: '' at test.pl line 7
It is the "close" statement. So we can take that out.
use strict;
use autodie;
open my $fh, '-|', 'bash -c "echo Hello; exit 1"';
print <$fh>;
#close $fh;
my $status = $? >> 8;
print "$status\n";
Now it is broken differently---it has lost the exit status:
Hello
0
I need to call close in order to get the exit status of a pipe.
So now I have settled on this ugly thing:
use strict;
use autodie;
open my $fh, '-|', 'bash -c "echo Hello; exit 1"';
print <$fh>;
{no autodie;
close $fh;}
my $status = $? >> 8;
print "$status\n";
That seems to work, but I'm not doing any error checking on the close statement:
Hello
1
Can I use close with autodie when my pipe fails? If not, how should I check for errors?
