Maybe I'm a hoarder. My timestamped histories from four machines in four different locations added up to 898028 lines --- I kept most of my shell commands, including errors and iterative attempts to get a good command, since early 2009 in the servers that matter the most to me. I use named shells with different histories each (roughly one to four shells per project), so the largest single shell history in these logs is only 43424 lines (21712 commands). The average across all shells is a bit over 75 logged commands per day, which doesn't sound as bad as the total line count in these histories. Despite the advent of LLMs I still need a lot of internal esoteric hacks that are relatively easy to find in these histories. Perhaps I should switch to using a centralized db that keeps the outputs as well and use them to finetune LLMs, but the ease of simple unix/Emacs tools operating with standard/simple history files always felt attractive.
