Bash Conditional Expressions

Simple Bash Script with TUI framework

Project overview

This project is a collection of Bash conditional-expression exercises and one Bubble Tea TUI application that wraps the tasks in an interactive terminal interface.

The main TUI app lives in bubbletea_tui/.

Main features

• number classification with Bash conditions
• file validation checks
• student name validation
• grade classification
• simple menu workflow with case
• assignment validation for submission folders
• log audit / regex / pipeline demo

Credits

• Bubble Tea TUI by Charmbracelet
• Bubbles and Lip Gloss by Charmbracelet
• original shell expression practice structure from the shell_expr_project

Project files

• bubbletea_tui/ — main interactive TUI app
• latihan_1.sh to latihan_5.sh — condition/test practice scripts
• studi_kasus_validasi_tugas.sh — submission validation example
• audit_log.sh — combined audit/log example
• tugas.sh — supporting task script

How to run

Linux distributions

1. Install Bash and Go.

   Debian/Ubuntu:

   sudo apt update
   sudo apt install bash golang-go

   Fedora:

   sudo dnf install bash golang

   Arch Linux:

   sudo pacman -S bash go

2. Run the TUI:

   cd bubbletea_tui
   go mod tidy
   go run .

3. Controls:

   • ↑/↓ or j/k to navigate
   • Tab to switch fields
   • Enter or r to run
   • e to export result
   • Esc to go back
   • q to quit

Windows

Recommended: use Windows Terminal with PowerShell, Git Bash, or WSL.

1. Install Go for Windows from https://go.dev/dl/
2. Open a terminal in the project folder.
3. Run:

   cd bubbletea_tui
   go mod tidy
   go run .

If the terminal UI looks odd in old CMD, switch to Windows Terminal or Git Bash.

Simple usage notes

• The TUI is the main entry point for exploring the project interactively.
• The Bash scripts can still be run directly if you only want the CLI exercises.
• The project is designed for teaching Bash test operators and conditional expressions.

Example direct Bash script usage

chmod +x *.sh
./latihan_1.sh
./latihan_2.sh
./latihan_3.sh
./latihan_4.sh
./latihan_5.sh
./studi_kasus_validasi_tugas.sh
./audit_log.sh sample.log ERROR

Warning

• go run . must be executed inside bubbletea_tui/.
• Some scripts expect specific input values or files.
• If you run audit_log.sh, make sure the log file exists.
• For best TUI experience, use a modern terminal emulator.
