Linux Yak First (Part 4): There’s no place like /home

export PATH=$HOME/bin:$PATH

Configuration in $HOME

As you learn more about linux configuration files, I find it helps to remember that linux’s roots come from systems designed around having multiple, concurrent users. Windows and OS X can do this as well these days, but this has been a normal part of linux for a long time now, and it shaped some of how things work.

  • Firefox’s configuration, cache, and profiles all live in .mozilla/firefox/.
  • Your SSH key and SSH configuration files live in .ssh/.
  • vim uses .vimrc for configuration, and a .vim directory for even more configuration.
  • .cache/ for caches, and
  • .local/ for data (like profiles, history, and potentially private data.)
  • .cache/, .config/ and .local/
  • .gitconfig — if you’re using git, then you should configure git.
  • .profile — this is similar to .bashrc, but it’s only read once (on login) instead of every time a terminal is opened.
  • .vimrc — everyone should learn at least some vim, including how to configure it.
  • .xinitrc — this file is read when you log in and lets you control which applications get launched when you login.
