Linux hacks for mouse-haters

Things I forget how to do in linux.

Some of these commands are supposed to be run sudo root, and each may irremediably fuck up your computer, your life, and everything you have ever loved. Then it might challenge you to a break dance battle, I dunno. It won’t be my fault.

Open a file in the GUI from the command line

xdg-open filename.ext

Of course! Why did I not realise that open is spelled xdg-open? For the curious, xdg stands for “Expect Delays Googling”, which is how you work out these unintuitive and unhelpful command names.

Must secure boot be disabled?

Talking to windows filesystems

Actually worth doing and I really should write down how I did it but deadlines…

Short version: NTFS can be whipped into providing a POSIX-compatible FS, with OK performance and is a good interchange system on a dual-boot windows/linux maachine. (although I don’t know how to make it encrypt) FAT32 is a permissions nightmare and causes all sorts of nasty issues.


Logical Volume manager has been current for a decade, which means that it is one decade newer than what I’m used to.
