Quick Tip

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

Challenge: When running commands or scripts, you often get both standard output (stdout) and standard error (stderr) messages. If you want to capture all of this information into a single log file, you need a way to merge them.

The Solution: Redirect both stdout and stderr to a file using the `2>&1` syntax.

your_command_here > output.log 2>&1

Why it works: `>` redirects stdout to `output.log`. `2>&1` then redirects stderr (file descriptor 2) to the same place as stdout (file descriptor 1). This ensures all output, including error messages, goes into one place.

Pro-Tip: For appending to a log file instead of overwriting, use `>>` instead of `>`: `your_command_here >> output.log 2>&1`
