Quick Tip

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

Challenge: When running commands or scripts that produce both standard output (stdout) and standard error (stderr), it can be difficult to manage or analyze both streams of information effectively, especially when redirecting output to a file.

The Solution: Redirect both standard output and standard error to a single stream using the `2>&1` construct.

your_command &> output.log

Why it works: The `&>` operator is a shorthand for `> output.log 2>&1`. This redirects both file descriptor 1 (stdout) and file descriptor 2 (stderr) to file descriptor 0 (which is then effectively treated as stdout when redirecting to a file), consolidating all output into one place.

Pro-Tip: For appending to an existing log file instead of overwriting it, use your_command &>> output.log.
