time command in Linux showing script execution time
Quick Linux Tip #4:

Try: time ./backup.sh

Info: The time command shows execution time. real is wall clock time, user is CPU time for the program, and sys is CPU time for system calls.

Examples:

  • $ time ./deploy.sh
  • $ /usr/bin/time -v ./process.py
  • $ time tar -czf backup.tar.gz /home/data

Note: Use /usr/bin/time -v for detailed resource usage, including memory.
