Quick Tip

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

Challenge: When running commands or scripts that produce both standard output (stdout) and error output (stderr), it can be difficult to manage and analyze them separately, especially when trying to capture all output for logging or debugging.

The Solution: Redirect both stdout and stderr to a single destination using the `2>&1` shell construct.

your_command_here > output.log 2>&1

Why it works: `>` redirects stdout to `output.log`. `2>&1` then redirects file descriptor 2 (stderr) to the current location of file descriptor 1 (stdout), effectively merging them into the same log file.

Pro-Tip: You can also use `&>` as a shorthand for `&> output.log 2>&1` to redirect both stdout and stderr to a file (note this is a bashism and might not be portable to all shells).
