Jniexec

As a software review, it can be said that Jniexec, which is Java's Runtime.exec(), is not as efficient as the management facilities available for sub processes on a UNIX/Linux system. This is because the sub processes provided by any POSIX shell or the underlying C library and system calls work better than Jniexec. In fact, there are several related feature requests in SUN's Java bug database due to its unsatisfactory performance.

Developers may have to wait for an official fix for Jniexec for a few more decades since it is challenging to devise a solution that is compatible with all systems. However, the good news is that developers interested in Linux (Unix) machines can use Jniexec to shorten the waiting time for an effective solution.

Jniexec provides a Java Native Interface wrapper around the fork and execlp pair of functions, and it comes with two easy-to-use Java wrapper classes. With Jniexec, developers can access the following features:

- A convenient way to run sub processes from within Java code
- A wrapper class for the system() command
- A wrapper class for the shell() command

In conclusion, Jniexec is an excellent solution for Linux (Unix) machines, and developers can use it to run sub processes efficiently from within Java code. It may not be the best solution available for all systems, but it is an effective one for those who want to save time and achieve better results.
