ls /usr/share/man/man?/*
will show you all the man pages on your system. I used to pick ones at random.
Originally there were a number of manuals. Manual 1 had user commands. Manual 2 had system calls. Etc. You can type man NUMBER intro
to read about that manual. You can also use man -k
or appropos
but I've also just used grep. These days they're compressed so zgrep.
I have never heard proper reasoning for squashing commits. I don't think sanitized history is useful in any context. Seeing the thought process that went into building something has been repeatedly useful in debugging things. It's also useful to me as a software engineering manager to help folks on my team get better. I could care less how "pretty" git log looks, but I care a hell of a lot about what git diff and git blame tell me. They help me figure out where issues actually are and how they came to be.
I use vcsh to manage my home directory - including but not limited to dot files. Written a number of posts on it over the years: https://phrye.com/tags/vcsh/
