I have a weird story about that.
When I was a junior sysadmin I worked for a company providing a SaaS solution for e-commerce.
The environment I worked in was bare-metal (as was the style at the time), with a 2 tier network architecture, lots of internal tooling (mostly in Perl fwiw) and highly complex interactions between components (cache items recorded in MySQL, centralised job control through a pair of activeMQ servers that had a postgres proof of record etc).
During this time, I fancied myself the growing expert, and thus I created the most gnarly one-liners you could imagine. But they did everything. I annotated them with a “function parameter” comment at the end
$ if []; then x; fi ## FUNCTIONDOES: THING
The existing team was disgruntled and started leaving, eventually making me the most senior in the team.
Of course, I also left.
I kept good contact with the team that onboarded as I was leaving, and one day while drinking I was told (off-handedly but in no uncertain terms) that I was the author of “the bash_history”.
After enquiring to what they meant, they indicated that after I resigned, someone found my bash_history file (because I had been onboarding them and they had seen my workflow) and it had been immortalised by:
A) Being copied to everyones profile and placed in /etc/skel
B) being chattr +i (immutable)
I was honoured. and horrified.
Physical deployment with an operating system that ran on hardware directly.
The only management interface being the very anaemic out of band management controller.
Another option is to make functions, aliases, or scripts as a way of saving those tricks. Not applicable to all tricks, but stuff like “embed all referenced fonts in a PDF file using `gs`” or “get me the ISO 8601 week using `date`” is way easier to use when you wrap it like this.
