+
+While chatting with one of [my WL colleague](https://twitter.com/foxlegend), I stumbled upon [Fish shell](https://fishshell.com/). 
+I immediately liked its autocompletion and extensibility mechanisms.
+After many years using [BASH](https://www.gnu.org/software/bash/) and [ZSH](https://zsh.sourceforge.io/), I therefore decided to move on to this new [shell](https://en.wikipedia.org/wiki/Unix_shell).
+
+Unlike the others, it's not [POSIX-compatible](https://fishshell.com/docs/current/fish_for_bash_users.html#fish-for-bash-users).
+
+Furthermore, to get (_at least_) the same functionalities as [OhMyZsh](https://github.com/ohmyzsh/ohmyzsh), I chose to install [StarShip](https://starship.rs/).
+
+I will then describe how I moved on and updated my existing tools such as [SdkMan](https://sdkman.io/).
+
+## FISH Installation
+
+{{< admonition info "OS" true >}}
+I applied these commands on both [Ubuntu20](http://ubuntu.com/)/[WSL2](https://learn.microsoft.com/fr-fr/windows/wsl/install) and [Linux Mint](https://linuxmint.com/). 
+{{< /admonition >}}
+
+To install it, run this command:
+
+```jshelllanguage
+sudo apt install fish
+```
+
+You must also use a font available on the [NerdFonts website](https://www.nerdfonts.com/font-downloads). 
+By the way, you can also use the fonts available through your package manager. 
+
+For instance, I chose using [JetBrains Mono](https://github.com/ryanoasis/nerd-fonts/releases/download/v3.0.2/JetBrainsMono.zip) 
+
+After downloading it, you can reload your font cache running this command:
+
+```jshelllanguage
+fc-cache -fv
+```
+## StarShip installation
+
+I ran this command:
+```jshelllanguage
+curl -sS https://starship.rs/install.sh | sh
+```
+
+{{< admonition info "How to update StarShip" true >}}
+To update StarShip, you must use the same command.
+{{< /admonition >}}
+
+I also added the following command at the end of ``~/.config/fish/config.fish``:
+
+```shell
+starship init fish | source
+```
+Due to some WSL2 incompatibilities, I also chose to use [the plain text presets](https://starship.rs/presets/plain-text.html) running this command:
+
+```jshelllanguage
+starship preset plain-text-symbols -o ~/.config/starship.toml
+```
+
+## SDKMAN update
+At this stage, SdkMan didn't work at all. To put it alive again, I had to install [Fisher](https://github.com/jorgebucaran/fisher) and a [SdkMan for fish plugin](https://github.com/reitzig/sdkman-for-fish).
+
+### Fisher install
+Run this command:
+```jshelllanguage
+curl -sL https://raw.githubusercontent.com/jorgebucaran/fisher/main/functions/fisher.fish | source && fisher install jorgebucaran/fisher
+```
+### SdkMan for fish plugin
+Run this command:
+```jshelllanguage
+fisher install reitzig/sdkman-for-fish@v2.0.0
+```
+### Run SdkMan 
+Run this command:
+
+```jshelllanguage
+sdk ug
+```
+Say yes and restart a shell.
+Now it should work.
+
+## NVM
+I had the same issue with [NVM](https://github.com/nvm-sh/nvm).
+
+I then installed another plugin with Fisher:
+
+```jshelllanguage
+fisher install jorgebucaran/nvm.fish
+```
+
+## GnuPG 
+I use [GnuPG for signing my GIT commits](https://blog.touret.info/2019/08/09/verifier-les-commit-git-avec-gpg/).
+Installing Fisher broke my setup.
+
+I then added this new configuration file ``$HOME/.config/fish/conf.d/config_gpgagent.fish`` with the following content:   
+
+```jshelllanguage
+set -gx GPG_TTY /dev/pts/0
+```
+To activate it, restart your shell (again).
+
+## Conclusion
+I can now use FISH for my daily job.
+As I said first, this article is only a reminder for my next setups (aka when I will broke my GNU/Linux boxes and try to restore them).
+
+Hope it will help you!
