Silent and Unattended CLI Execution Skill

Overview

This skill provides a comprehensive reference for running command line programs in unattended/non-interactive environments. It documents environment variables, command-line flags, and configuration options to:

Disable interactive prompts - Ensure programs run without user input
Suppress progress indicators - Disable spinners, progress bars, and real-time updates
Disable colored output - Remove ANSI color codes and terminal formatting
Reduce output verbosity - Limit output to essential information only
Force non-TTY mode - Prevent programs from detecting terminal capabilities

Coverage

155 programs across Linux, macOS, and Windows
Cloud platforms, containers, version control, build tools, databases, security, monitoring, CI/CD, IaC, and more

Universal Environment Variables

These environment variables affect many programs:

Variable	Value	Effect
`CI`	`true`	Indicates continuous integration environment, triggers non-interactive mode for many tools
`DEBIAN_FRONTEND`	`noninteractive`	Prevents apt/dpkg from prompting (Debian/Ubuntu)
`FORCE_COLOR`	`0`	Disables colored output (Node.js, some JS tools)
`NO_COLOR`	`1`	Disables colored output (growing standard)
`TERM`	`dumb`	Minimal terminal capabilities
`TZ`	`UTC`	Sets timezone, prevents timezone prompts
`PYTHONUNBUFFERED`	`1`	Unbuffered Python output
`NODE_NO_WARNINGS`	`1`	Suppress Node.js warnings
