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) messages. If you want to capture all of this information into a single log file, it can be cumbersome.
The Solution: Use the `2>&1` redirection operator to merge stderr into stdout before redirecting to a file.
your_command_here > output.log 2>&1
Why it works: `>` redirects stdout (file descriptor 1) to `output.log`. `2>&1` then redirects stderr (file descriptor 2) to wherever stdout is currently pointing (which is `output.log`).
Pro-Tip: For appending to the log file instead of overwriting, use `>>` for stdout: your_command_here >> output.log 2>&1
