Simple way to gather system and kernel informations from your Unix / Linux system

The Proc File System can be used to gather useful information about the system and the running kernel.
Some of the important files are listed below

• /proc/cpuinfo - information about the CPU (model, family, cache size etc.)

• /proc/meminfo - information about the physical RAM, Swap space etc.

• /proc/mounts - list of mounted file systems

• /proc/devices - list of available devices

• /proc/filesystems - supported file systems

• /proc/modules - list of loaded modules

• /proc/version - Kernel version

• /proc/cmdline - parameters passed to the kernel at the time of starting
