Quick Tip

Harness `stdbuf` for Unbuffered Command Output

Challenge: When running commands that buffer their output, especially in scripts or pipelines, you might not see the output in real-time, making debugging or monitoring difficult.

The Solution: Use the `stdbuf` command to control the buffering behavior of commands.

stdbuf -o L your_command_here

Why it works: The `-o L` option tells `stdbuf` to set the standard output stream to line buffering, ensuring that output is flushed after each line is written, making it visible immediately.

Pro-Tip: You can also use `-e L` for standard error and `-i L` for standard input if needed.
