Using CAT for concatenating files broken down via HJSplit

My friend Bu wanted to share with me a large 3GP file. However, attaching large files in email is limited (20MB or so in Gmail), so we needed to split the files. I have been using WinRAR to split files, but he is using HJSplit.



Oh, and I'm on Ubuntu.

I tried to look for an HJSplit equivalent for ubuntu, but I can't find anything useful. Somewhere, I've read that if the files are not compressed when split, you can use CAT to recombine them.




Here is the syntax:

Assuming the files are named filename.zip.001, filename.zip.002, filename.zip.003, etc etc, use this command to recombine them into one big happy file.

cat filename.zip.* > filename.zip

There goes!
