Quick Tip

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

Challenge: When running commands or scripts, you often see error messages (stderr) and normal output (stdout) appearing separately in your terminal. This can make it difficult to read logs or redirect both types of output to a single file for analysis.

The Solution: Redirect both standard error (stderr) and standard output (stdout) to the same destination using the `2>&1` redirection operator.

your_command_here &> output.log

Why it works: The `&>` operator is a shorthand for `> output.log 2>&1`. It redirects file descriptor 1 (stdout) to the file `output.log` and then redirects file descriptor 2 (stderr) to the same location as file descriptor 1.

Pro-Tip: For older shells or if you prefer more explicit syntax, you can use `your_command_here > output.log 2>&1`.
