is there a reliable cross-platform method for testing if a file is compressed?

[it_says_BALLS_on_your_forehead]

I've tried using Solaris's 'file' command, which seems to work ok on my
2 sample files, but on AIX, I get different results for two different
files that are gzipped.

One result reads : gzip (.gz) compressed data
The second is : data or International Language text

both files are gzipped.

....so, I was wondering if there existed a reliable, consistent way of
testing the file_type of a file within Perl that would not vary across
OS.

You mean, *besides* File::Mimeinfo, which a simple CPAN search
would have shown you?

If you didn't look, shame on you.

If you *did* look, what's wrong with that module?

print "Just another Perl hacker,"; # the original

Shame on me.

I'll check it out. Thanks Randall.
