We do have many tools sections that offer a wide range of OS tools including Linux.
I would say the sections of "
Hacking Tools" is what can be used for any Linux-based programs/scripts/etc.
Keep in mind that you can post tools that aren't directly related to hacking yet don't drift too far on that keeping the overall content relative at some point.
Yet Linux is widely used for hacking so I wouldn't argue that all such threads will be unrelated.
