Extracting SFX files in Linux

Use unrar to extract files from RAR SFX archives.

Like this: unrar x filename.sfx

For Linux Ubuntu 12.04 the following works:

$ chmod +x some_file.part1.sfx

$ ./some_file.part1.sfx

In Nautilus (File Browser), rename the .sfx part to .rar, then right-click and extract. Or double-click for more options.
