Tudor's custom bash setup

My personal Bash configuration for Linux: a clean prompt, a smarter cd, a nicer cat, and a system summary every time I open a terminal.

What's inside

• Prompt: Oh My Posh with a custom theme (oh-my-posh/config.omp.json)
• Navigation: zoxide for jumping between directories
• Viewing files: cat is aliased to bat
• Greeting: fastfetch on every new terminal
• History: 10,000 entries, duplicates ignored, appended across sessions
• PATH setup: pipx, pnpm, Homebrew (Linuxbrew) and LM Studio CLI Every tool is wrapped in a command -v check, so if something isn't installed, the shell simply skips it instead of throwing errors.

Requirements

Required for the full experience:

Tool	Purpose
oh-my-posh	prompt
zoxide	smart cd
bat	cat replacement
fastfetch	system info on startup

For oh-my-posh, follow the official installation guide or use your AUR helper of choice.

You also need a Nerd Font set in your terminal emulator, otherwise the prompt icons won't render properly.

Installation

Supported distros: Arch, Debian/Ubuntu, Fedora and openSUSE.

git clone https://github.com/tudorioan1/mybash.git ~/mybash
cd ~/mybash
chmod +x install.sh
./install.sh

The script detects your package manager (pacman, apt, dnf or zypper), installs the dependencies (zoxide, bat, fastfetch, oh-my-posh) and symlinks the config files into place. Anything already there is moved to <file>.bak.<timestamp>, never deleted.

Options:

Flag	What it does
--no-deps	only link the config files, don't install packages
-y, --yes	don't ask for confirmation before installing
-h, --help	show help

Then open a new terminal or run source ~/.bashrc.

oh-my-posh is installed with its official installer, which is downloaded and run with curl | bash. Use --no-deps and install it yourself if you'd rather not.

Manual installation

git clone https://github.com/tudorioan1/mybash.git ~/mybash
cd ~/mybash

# Back up your current config
[ -e ~/.bashrc ] && mv ~/.bashrc ~/.bashrc.bak
[ -e ~/.config/oh-my-posh ] && mv ~/.config/oh-my-posh ~/.config/oh-my-posh.bak
[ -e ~/.config/fastfetch ] && mv ~/.config/fastfetch ~/.config/fastfetch.bak

# Link the files into place
mkdir -p ~/.config
ln -s "$PWD/.bashrc" ~/.bashrc
ln -s "$PWD/config/oh-my-posh" ~/.config/oh-my-posh
ln -s "$PWD/fastfetch" ~/.config/fastfetch

# Reload
source ~/.bashrc

Install the dependencies (zoxide, bat, fastfetch, oh-my-posh) with your package manager. On Debian/Ubuntu bat is called batcat, so also run mkdir -p ~/.local/bin && ln -s "$(command -v batcat)" ~/.local/bin/bat.

Symlinks mean that any edit you make in the repo is live immediately, and you can git pull to update.

Customization

• Prompt theme: edit oh-my-posh/config.omp.json. See the Oh My Posh docs.
• Aliases: the Aliases section of bashrc. The tarafetch alias runs countryfetch Romania, so change it to whatever you like.
• Less noise on startup: remove or comment out the fastfetch block at the bottom.
• Paths: everything uses $HOME, so nothing needs changing for a different username.
