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 if they are interleaved or directed to different locations. This is especially true when trying to redirect output to a log file.

The Solution: Redirect both standard error (stderr) and standard output (stdout) to a single destination using the `2>&1` redirection operator.

your_command_here > output.log 2>&1

Why it works: The `>` redirects stdout to `output.log`. Then, `2>&1` redirects file descriptor 2 (stderr) to the current location of file descriptor 1 (stdout), effectively merging them. This ensures all output, both normal and error messages, are captured in the same file.

Pro-Tip: You can also use `>&` as a shorthand for `> … 2>&1` in many shells for even quicker redirection.
