Change WSL font from inside WM?

14. 6. 2025

Get the path

# get linux path to windows %LOCALAPPDATA%
# and assume the rest is hardcoded
wslpath="$(wslpath "$(cmd.exe /c "echo %LOCALAPPDATA%\Packages\Microsoft.WindowsTerminalPreview_8wekyb3d8bbwe\LocalState" | tr -d '\r')")"

# All these methods assume WSL is installed under the 'current user profile' (not as system-wide).
cd "$wslpath" || exit

pwd

head settings.json

Assumes current user profile type of installation …

Figure out the guid manually by inspecting the settings.json. (There should be a way to do this automagically, but my ‘Bookworm’ is not listed in ‘wsl –list’ for some reason)

"guid": "{1cd9302d-337e-54e1-bb87-c45069dc5a47}", < This
"hidden": false,
"icon": null,
"name": "bookworm (12)",
"scrollbarState": "hidden",
"source": "Windows.Terminal.Wsl"
etc ...

Do the jq magic

cp settings.json setting.json.bak || exit # backup
jq '(.profiles.list[] | select(.guid == "{1cd9302d-337e-54e1-bb87-c45069dc5a47}")).font.face = "Fira Code"' settings.json > tmp.json && mv tmp.json settings.json
