Quick Tip

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

Challenge: When running commands or scripts, it’s common to have both standard output (stdout) and standard error (stderr) messages. If you want to capture both into a single file for analysis or logging, it can be cumbersome.

The Solution: Use the `2>&1` redirection operator to merge stderr into stdout.

your_command > output.log 2>&1

Why it works: The `>` redirects stdout (file descriptor 1) to `output.log`. The `2>&1` then redirects stderr (file descriptor 2) to the same place where stdout is currently going (which is `output.log`).

Pro-Tip: You can also use `&>` as a shorthand for `2>&1` in bash, so `your_command &> output.log` achieves the same result.
