How to Restart Perl on CentOS
Perl is a scripting language first developed by Larry Wall. It is freely available on a number of platforms, including CentOS. When a Perl application runs, the Perl interpreter is first called to process and understand the code and translate it into a workable form that the machine can understand. Sometimes the Perl process can lock up and will need to be terminated. You can terminate and re-launch Perl on CentOS using built-in operating system commands.
