Quick Tip

Redirect stderr to stdout for Unified Logging

Challenge: When troubleshooting or monitoring complex commands or scripts, you might encounter error messages (stderr) and standard output (stdout) getting mixed or going to different places, making it difficult to get a consolidated view of what’s happening.

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

your_command &> output.log

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

Pro-Tip: For more granular control, you can use `your_command > stdout.log 2> stderr.log` to separate stdout and stderr into different files.
