Quick Tip

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

Challenge: When running commands or scripts, you often have both standard output (stdout) and standard error (stderr) streams. Separating these can make log analysis cumbersome, especially when you want to capture all output in a single file.

The Solution: Redirect both stdout and stderr to a single destination.

command > output.log 2>&1

Why it works: The `> output.log` redirects standard output to `output.log`. The `2>&1` then redirects file descriptor 2 (stderr) to the same location as file descriptor 1 (stdout), effectively merging both streams.

Pro-Tip: For a slightly more concise version that achieves the same result, you can use command >& output.log.
