Quick Tip

Tame 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 and analyze them separately. Often, you want to consolidate them into a single log file for easier review.

The Solution: Use the `2>&1` redirection operator to merge stderr into stdout.

your_command &> output.log

Why it works: The `&>` operator is a shorthand that redirects both stdout (file descriptor 1) and stderr (file descriptor 2) to the specified file. This is a convenient way to capture all output from a command.

Pro-Tip: For more granular control, you can use `command_that_produces_output > stdout.log 2> stderr.log` to send stdout and stderr to different files, or `command &> /dev/null` to discard all output.
