Quick Tip

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

Challenge: When running commands or scripts that produce both standard output (stdout) and standard error (stderr), it can be difficult to manage or analyze these outputs separately, especially when trying to capture all relevant information in a log file.

The Solution: Redirect both standard output and standard error to a single file using the `2>&1` syntax.

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 wherever stdout is currently being directed, effectively merging both streams into one file.

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