Quick Tip

Redirecting `stderr` to `stdout` for Unified Logging

Challenge: When running commands, you often get output on both standard output (stdout) and standard error (stderr). This can make it difficult to capture all output in a single log file or pipe it to another command.

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

your_command &> output.log

Why it works: The `&>` operator is a shorthand for `&1 >&2`, which redirects both stdout (file descriptor 1) and stderr (file descriptor 2) to the specified file. If you wanted to be more explicit or redirect to a specific file descriptor, you’d use `your_command > output.log 2>&1`.

Pro-Tip: For interactive sessions where you want to see output on the terminal but still log it, use the `tee` command: `your_command 2>&1 | tee output.log`
