Quick Tip

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

Challenge: When running commands in the Linux terminal, standard output (stdout) and standard error (stderr) are often displayed separately. This can make it difficult to process or log command output consistently, especially in scripts.

The Solution: Redirect both standard error and standard output to a single destination.

your_command 2>&1 | tee output.log

Why it works: The `2>&1` syntax redirects file descriptor 2 (stderr) to the same location as file descriptor 1 (stdout). Piping this combined output to `tee` then sends it to both the console and the specified log file (output.log in this case).

Pro-Tip: For simple redirection to a file without seeing it on the console, you can use `your_command > output.log 2>&1`.
