Note:If you have the kernel documentation installed (linux-docs), you can find detailed information about sysctl settings in/usr/lib/modules/$(uname -r)/build/Documentation/admin-guide/sysctl/. It is highly recommended reading these before changing sysctl settings. ...
It talks with the Linux system control interface, which allows reading and writing to the available settings. These settings we call key-value pairs. So when referring to a sysctl key, we mean the setting by its name (e.g. vm.panic_on_oom). We can query the values with the sysctl ...
