Quick Tip

Taming Terminal Noise: Unified Logging with `2>&1`

Challenge: When running commands or scripts, you often want to capture both standard output (stdout) and standard error (stderr) into a single log file for easier analysis and debugging. By default, these go to separate streams.

The Solution: Redirect both stdout and stderr to the same file using the `2>&1` redirection operator.

your_command_here > output.log 2>&1

Why it works: The `>` redirects stdout (file descriptor 1) to `output.log`. Then, `2>&1` redirects stderr (file descriptor 2) to the same destination as stdout (file descriptor 1). This ensures all output, including error messages, is consolidated.

Pro-Tip: Use `>>` instead of `>` to append to the log file instead of overwriting it each time.
