General Shell Configuration
General Shell Configuration
As you may have noticed with my 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 $HOME/.profile file which mainly exports environment variables.
Despite the fact Fish is not a POSIX shell and should not be able to
read it, the plugin foreign-env comes in handy to load this .profile
from fish, as you can see in my fish config.
The correctness and POSIX compatibility of this file is verified using shellcheck.
Before we go into the meaty stuff, let me first load some private configuration I cannot share online.
# shellcheck source=/dev/null
. "$HOME"/.profile.privatePersonal Information
First of all, here I set some information in order to make some stufff work.
| Variable | Value |
|---|---|
EMAIL |
lucien@phundrak.com |
NAME |
"Lucien Cartier-Tilet" |
<<export-variables(personal-info)>>XDG variables
Then, let me set some XDG variables that may not be set by default, but are still quite useful.
| Variable | Value |
|---|---|
XDG_CACHE_HOME |
"$HOME"/.cache |
XDG_CONFIG_HOME |
"$HOME"/.config |
XDG_DATA_HOME |
"$HOME"/.local/share |
XDG_STATE_HOME |
"$HOME"/.local/state |
<<export-variables(xdg-variables)>>Dev
Here are some variables that are quite useful.
| Variable | Value | Value is a command? |
|---|---|---|
SSH_AUTH_SOCK |
gpgconf --list-dirs agent-ssh-socket |
yes |
LD_LIBRARY_PATH |
"$LD_LIBRARY_PATH":/usr/local/lib |
|
LSP_USE_PLISTS |
true |
|
DIFFPROG |
ediff |
|
SUDO_ASKPASS |
"$HOME"/.local/bin/askpass |
|
MANPAGER |
less |
-
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 ediff.
-
SUDO_ASKPASS - which script to call when calling
sudo -A. It uses my script askpass.
<<export-variables(dev-variables)>>Android development
I’m not sure why I keep these, honestly.
| Variable | Value |
|---|---|
DART_SDK |
/opt/dart-sdk/bin |
ANDROID_HOME |
"$HOME"/Android/Sdk |
CHROME_EXECUTABLE |
/usr/bin/chromium |
<<export-variables(android)>>
Compatibility issues with MANPAGER
Due to compatibility issues with using less as the pager for man, some
variables must be redefined.
| Variable | Value | Value is a command? |
|---|---|---|
LESS_TERMCAP_mb |
printf '\e[1;32m' |
yes |
LESS_TERMCAP_md |
printf '\e[1;32m' |
yes |
LESS_TERMCAP_me |
printf '\e[0m' |
yes |
LESS_TERMCAP_se |
printf '\e[0m' |
yes |
LESS_TERMCAP_so |
printf '\e[01;33m' |
yes |
LESS_TERMCAP_ue |
printf '\e[0m' |
yes |
LESS_TERMCAP_us |
printf '\e[1;4;31m' |
yes |
<<export-variables(less-termcap)>>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.
| Variable | Value |
|---|---|
BROWSER |
firefox |
<<export-variables(browser)>>Editor variables
My favourite text editor is Emacs, in case you haven’t guessed
already. It makes sense that both my EDITOR and VISUAL variables
should be set to Emacs.
| Variable | Value |
|---|---|
EDITOR |
"emacsclient -c" |
VISUAL |
"emacsclient -c" |
<<export-variables(editor)>>GTK Theme
These are some important variables regarding the GTK theme I use.
| Variable | Value |
|---|---|
GTK_THEME |
Nordic |
GTK_ICON_THEME |
"Flat-Remix-Dark" |
<<export-variables(gtk)>>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.

I also need to export this alias, because wget feels like it’s
special, but these are exported in wrappers in my scripts
documentation.
If you’re wondering how I got most of these variables, xdg-ninja can help you with that.
