Maybe around 2006, I booted a live CD of Ubuntu and ran the 6 disc install of Unreal Tournament 2004 so that I could play UT with a friend who was staying over - the laptop was my mum’s, so I wasn’t allowed to install anything directly on it. UT2004 had a native Linux version on disc.
The install took until 4am and we played until the sun came up, absolute bliss getting it working.
My favourite one is renaming a directory full of files in
nnn
. It opens in vim, and I’m in my happy place, where I really know how to edit text (or, in this case, filenames). Great when there’s some minor variation between a lot of files. Full previewing before saving, multiple operations handled before doing anything etc.
