Quick Tip

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

Challenge: When running commands or scripts, standard output (stdout) and standard error (stderr) are often interleaved or sent to separate destinations, making it difficult to analyze logs effectively, especially when redirecting output to a file.

The Solution: Use the `2>&1` redirection operator to send both standard error and standard output to the same destination.

your_command_here > output.log 2>&1

Why it works: File descriptor `1` represents stdout, and `2` represents stderr. By redirecting `2` to `1` (`2>&1`), you ensure that all error messages are sent to wherever stdout is currently directed (in this case, `output.log`).

Pro-Tip: To also include command output in a `tee` command for real-time viewing and logging, use: your_command_here 2>&1 | tee output.log
