Subject: One liner for filenames

Hello,
Can someone help me to write a Ruby one-liner to remove all the files
except one in a list of files? I have a list of pages of an original
PDF. Each page has been converted to a PNG file. They're each numbered
with an underscore and a number at their end.

filename_1.png
filename_2.png
filename_3.png
...

I need to basically delete all of the files except for the first one,
the one with the "_1" suffix at the end. Can I do that wiith a
one-liner?

Thanks,
Peter
