Quick Tip

Unified Logging with `2>&1`

Challenge: When troubleshooting or monitoring applications, you often need to capture both standard output (stdout) and standard error (stderr) to get a complete picture of what’s happening. Separately managing these streams can be cumbersome.

The Solution: Redirect standard error to standard output using the `2>&1` shell construct.

your_command &> output.log

Why it works: The `&>` redirection is a shorthand that redirects both stdout (file descriptor 1) and stderr (file descriptor 2) to the specified file. This ensures all output, including error messages, is captured in a single log file.

Pro-Tip: For more granular control, you can use `your_command 1> output.log 2> error.log` to send stdout and stderr to separate files, or `your_command > output.log 2>&1` to send stdout to `output.log` and then append stderr to the same file if you want stdout to come first.
