Hello Monks, I have a file that looks like this:

(3.3.3.3,4.4.4.4,)
[download]

What I need to do is get rid of the comma at the end. I tried using sed, like this:

system "sed 's/,)/)/' pbxiplp > pbxiplp1";
[download]

but, instead of giving me

(3.3.3.3,4.4.4.4)
[download]

, it just removes everything within the file. Any ideas? I've used 'sed' plenty in the past, but have never run into this before. The file will always only contain one line.
