Explanation

This file shows the parameters passed to the kernel at the time it is started. A sample /proc/cmdline file looks like the following: ro root=/dev/VolGroup00/LogVol00 rhgb quiet 3 /proc is very special in that it is also a virtual filesystem. It's sometimes referred to as a process information pseudo-file system. It doesn't contain 'real' files but runtime system information (e.g. system memory, devices mounted, hardware configuration, etc). For this reason it can be regarded as a control and information centre for the kernel. In fact, quite a lot of system utilities are simply calls to files in this directory.
