watch (Rust)

A Rust implementation of watch focused on making the tool platform-independent, including macOS support.

This project is modeled after the Linux watch implementation from procps-ng:

• https://gitlab.com/procps-ng/procps/-/blob/master/src/watch.c

Basics

Run a command repeatedly and show its output fullscreen.

watch -n 1 df -h .

Press:

• q to quit
• Ctrl+C to interrupt
• space to run immediately
• s to save a screenshot

Install

If Rust/Cargo is set up correctly, install this binary into your Cargo bin directory:

cargo install --path .

This installs watch to ~/.cargo/bin/watch by default. If your PATH is set up properly (for example includes ~/.cargo/bin), you can run:

watch --help
