Ubuntu Server Setup

This script updates Ubuntu, installs mosh, zsh, oh-my-zsh, Vim-mode and completion plugins, and configures jj as an insert-mode escape shortcut in Vim and the zsh prompt.

Usage

After the repository is published on GitHub, run it with one command:

curl -fsSL https://raw.githubusercontent.com/aprogramq/server-setup/main/ubuntu.sh | bash

Local run:

chmod +x ubuntu.sh
./ubuntu.sh

The script can be run as root or as a regular user with sudo access.

What It Installs And Configures

• system packages: ca-certificates, curl, git, mosh, tmux, vim, zsh
• oh-my-zsh
• oh-my-zsh plugins: git, vi-mode, zsh-autosuggestions, zsh-syntax-highlighting, zsh-completions
• ~/.vimrc: inoremap jj <Esc>
• ~/.zshrc: Vim mode and jj as Esc in the command line, VI_MODE_ESC_INSERT=jj, KEYTIMEOUT=25
• tmux autostart on SSH login: attaches to the main session or creates it
• ~/.tmux.conf: copy mode on Ctrl-b v, default Ctrl-b [ disabled, copy-mode scrolling with j/l, copying with y or Y to the local clipboard through OSC 52

After the shell is changed, log out and log back in.
