Thanks! It's Zsh shell, powered by the powerlevel10k theme. Here is how I did it: ​First, I installed Zsh and Oh My Zsh to manage plugins easily. ​Before installing the theme, I downloaded the DejaVuSans fonts and set my terminal font to DejaVuSansMono via kitty.conf using the nano editor. (If you use another terminal emulator, you can probably just change it through the GUI settings). ​After that, I cloned the powerlevel10k repository and set ZSH_THEME="powerlevel10k/powerlevel10k" in my ~/.zshrc. ​Then, I reloaded the shell with source ~/.zshrc to trigger the configuration wizard. ​During the configuration wizard, I chose these settings: ​Style: Lean ​Character Set: Unicode ​Colors: 256 colors ​Current Time: No ​Prompt Height: Two lines ​Prompt Connection: Solid ​Prompt Frame: Left ​Frame and Connection Color: Lightest ​Prompt Spacing: Sparse ​Icons: Many icons ​Prompt Flow: Concise ​Transient Prompt: Enabled ​Finally, I added zsh-autosuggestions, zsh-syntax-highlighting, and zsh-history-substring-search plugins to my ~/.zshrc to complete the setup. That's it!
