+
+* General Shell Configuration
+As you may have noticed with my [[file:./fish.md][Fish configuration]], my main shell is
+Fish, not Bash or Zsh. But sometimes, I do need to use these instead
+of Fish. In order to share some common configuration, I have a rather
+rich =$HOME/.profile= file which mainly exports environment variables.
+Despite the fact Fish is not a POSIX shell and should not be able to
+read it, the plugin =foreign-env= comes in handy to load this =.profile=
+from fish, as you can see [[file:./fish.md#global-variables][in my fish config]].
+
+The correctness and POSIX compatibility of this file is verified using
+[[https://www.shellcheck.net/][shellcheck]].
+
+Before we go into the meaty stuff, let me first load some private
+configuration I cannot share online.
+
+#+begin_src sh
+# shellcheck source=/dev/null
+. "$HOME"/.profile.private
+#+end_src
+
+** Personal Information
+First of all, here I set some information in order to make some stufff
+work.
+#+name: personal-info
+| Variable | Value                  |

+
+** XDG variables
+Then, let me set some XDG variables that may not be set by default,
+but are still quite useful.
+
+#+name: xdg-variables
+| Variable        | Value                |

+
+#+begin_src sh

+#+end_src
+
+** Dev
+Here are some variables that are quite useful.
+#+name: dev-variables
+| Variable        | Value                                | Value is a command? |

+
+- =SSH_AUTH_SOCK= :: allows me to use my local GPG keys when SSHing into a
+  remote host that may not have a gpg agent. It tells SSH which sock
+  to use, sock which allows SSH to interact with other software, here
+  GPG.
+- =LD_LIBRARY_PATH= :: path of libraries that may be included by
+  compilers such as GCC.
+- =LSP_USE_PLISTS= :: optimisation for LSP servers with Emacs.
+- =DIFFPROG= :: program used by software that wants to diff two files,
+  such as git. It uses my script [[file:./scripts.md#ediff][ediff]].
+- =SUDO_ASKPASS= :: which script to call when calling =sudo -A=. It uses
+  my script [[file:./scripts.md#askpass][askpass]].

+*** Android development
+I’m not sure why I keep these, honestly.
+
+#+name: android

+
+*** Compatibility issues with =MANPAGER=
+Due to compatibility issues with using =less= as the pager for man, some
+variables must be redefined.
+
+#+name: less-termcap
+| Variable        | Value               | Value is a command? |

+** Preferences
+*** Browser
+It’s always nice to have the =BROWSER= variable available in case you
+want to do stuff with scripts and your default browser.
+
+#+name: browser
+| Variable | Value   |
+|----------+---------|
+| =BROWSER=  | =firefox= |
+
+#+begin_src sh
+<<export-variables(browser)>>
+#+end_src
+
+*** Editor variables
+My favourite text editor is [[https://www.gnu.org/software/emacs/][Emacs]], in case [[file:emacs/index.md][you haven’t guessed
+already]]. It makes sense that both my =EDITOR= and =VISUAL= variables
+should be set to Emacs.
+
+#+name: editor
+| Variable | Value            |
+|----------+------------------|
+| =EDITOR=   | ="emacsclient -c"= |
+| =VISUAL=   | ="emacsclient -c"= |
+
+#+begin_src sh
+<<export-variables(editor)>>
+#+end_src
+
+*** GTK Theme
+These are some important variables regarding the GTK theme I use.
+
+#+name: gtk
+| Variable       | Value             |
+|----------------+-------------------|
+| =GTK_THEME=      | =Nordic=            |
+| =GTK_ICON_THEME= | ="Flat-Remix-Dark"= |

+#+begin_src sh
+<<export-variables(gtk)>>
+#+end_src
+
+** Cleaning up my home directory
+Home directories tend to become cluttered over time, especially when
+developers tend to not care about the XDG standard and throw their
+app’s files into =$HOME= rather than in =XDG_CACHE_HOME=, =XDG_CONFIG_HOME=,
+and so on. Fortunately, some software allow us to move their data
+elsewhere, so let’s teach them some manners.
