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 consolidate and analyze these messages, especially when redirecting output to a file.

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

your_command &> output.log

Why it works: The `&>` operator is a shorthand for `> file 2>&1`. It redirects both stdout (file descriptor 1) and stderr (file descriptor 2) to the specified file. This is incredibly useful for capturing all possible output from a command for later review or debugging.

Pro-Tip: For older shells or for more explicit control, you can use `your_command > output.log 2>&1`.
