Quick Tip

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

Challenge: When running commands in Linux, especially in scripts, error messages (stderr) and standard output (stdout) can get mixed up, making it difficult to analyze logs or capture all output in a single file.

The Solution: Redirect both standard error and standard output to a single destination using file descriptor redirection.

your_command > output.log 2>&1

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

Pro-Tip: To append to the log file instead of overwriting it, use `>>` instead of `>`: your_command >> output.log 2>&1.
