Shell prompt styles

• Fish (setup)
• PowerShell

~Fish.fish

set -U fish_color_host FA0
set -U fish_color_host_remote FA0
set -U fish_color_user normal
set -U fish_color_cwd normal

# If you're using the default prompt and don't have ~/.config/fish/functions/fish_prompt.fish, then run:
# fish_config prompt save default
# If that doesn't work and launches a web browser, then you have an older version of Fish, so you can instead run:
# mkdir -p ~/.config/fish/functions && cp /usr/share/fish/functions/fish_prompt.fish ~/.config/fish/functions/fish_prompt.fish
$EDITOR ~/.config/fish/functions/fish_prompt.fish
# Edit the script to change the $suffix value from ">" to "›" on line 10 or 11

~PowerShell.ps1

# Save this in the path returned by $PROFILE, for example, %USERPROFILE%\Documents\PowerShell\Microsoft.PowerShell_profile.ps1 (different depending on PS version).
# Compatible with both PowerShell 5 (built-in) and 7 (Core, installed separately).
# If the prompt ends with › instead of ›, try encoding this profile file with a UTF8 BOM instead of plain UTF8, to make Windows guess the encoding correctly. Needed on Windows 10, Server 2019, and Server 2022. ANSI(1252) or Windows 11 don't have this problem.
