How do you get IO::Uncompress::Gunzip to error if the input file isn't a GZ file?

Say I have files like:

dd if=/dev/random of=test.random bs=64 count=1 dd if=/dev/zero bs=64 count=1 echo "hello world!" > hello.txt

And my script is:

use IO::Uncompress::Gunzip qw(gunzip $GunzipError); my $output; my $status = gunzip $ARGV[0] => \$output, Strict => 1 or die "Failed!" +; print $GunzipError; print $output;

Then... test.random hello.txt

None of those will die or give error (well test.random will if you are really lucky...)

It seems to me that if the GZIP magic header is no present the input just copies to output instead of being error?

to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
