Quick Tip

Master `tee` for Split Output and Log Archiving

Challenge: You need to see the output of a command on your terminal while simultaneously saving it to a file for later review or logging.

The Solution: Use the `tee` command to duplicate command output.

your_command | tee output.log

Why it works: `tee` reads from standard input and writes to standard output and one or more files. This allows you to monitor the command’s progress in real-time on your terminal while ensuring a persistent record in the specified file.

Pro-Tip: Use `tee -a` to append to the log file instead of overwriting it: your_command | tee -a output.log
