Secrond

Secrond is a powerful lightweight cron implementation that offers users the ability to schedule programs to run at specific intervals. Unlike other cron daemons, Secrond can handle tasks in intervals of seconds, minutes, hours and days, making it a highly practical option for users.

While it is possible to achieve similar behavior by using a traditional cron daemon and adding sleep()s to the programs executed, it is often impractical. Secrond offers users a more streamlined and efficient way to execute time-sensitive tasks.

With only 10 entries in the schedule, Secrond reserves only about 400 bytes of memory, making it an ideal choice for users who need a cron implementation that doesn't hog system resources. Additionally, observation in tools like top show no significant CPU usage (0.0%), making it a highly efficient choice.

Secrond has undergone rigorous testing, including testing with valgrind, which has yielded positive results. According to valgrind, there are "no memory leaks possible," ensuring that users can trust Secrond to execute tasks without compromising system performance. Overall, Secrond is an excellent choice for users who need a reliable and efficient cron implementation.
