Quick Tip

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

Challenge: When running commands that produce both standard output (stdout) and error messages (stderr), it can be cumbersome to manage them separately, especially when trying to capture all output to a single log file.

The Solution: Redirecting both stdout and stderr to the same destination using the `2>&1` redirection operator.

your_command > output.log 2>&1

Why it works: This command first redirects standard output (file descriptor 1) to `output.log`. Then, `2>&1` redirects standard error (file descriptor 2) to wherever standard output is currently pointing, effectively merging both streams into a single file.

Pro-Tip: For interactive sessions where you want to see output on the screen but also capture it to a file, use the `tee` command: your_command 2>&1 | tee output.log
