Quick Tip
Tame 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 analyze them together, especially when redirecting output to a file or piping it to another command.
The Solution: Redirect both stdout and stderr to a single stream using the `2>&1` syntax.
your_command_here &> output.log # or your_command_here > output.log 2>&1
Why it works: File descriptor 1 (stdout) and 2 (stderr) represent the two primary output streams. `2>&1` tells the shell to redirect file descriptor 2 (stderr) to the same location as file descriptor 1 (stdout). The `&>` is a shorthand for this operation.
Pro-Tip: Use `| tee output.log` after your command to see the output in the terminal and save it to a file simultaneously.
