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

Challenge: When running commands or scripts, error messages (stderr) and regular output (stdout) are often displayed separately, making it difficult to capture and analyze them together, especially when redirecting output to a file.

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

your_command > output.log 2>&1

Why it works: `2` represents the file descriptor for standard error, and `1` represents standard output. `2>&1` tells the shell to redirect file descriptor 2 (stderr) to the same location as file descriptor 1 (stdout). Combined with `> output.log`, all output goes into `output.log`.

Pro-Tip: You can also use `&&` to chain commands so that the second command only runs if the first one succeeds: command1 > output.log 2>&1 && command2
