5.2. Top-level Files within the proc File System Below is a list of some of the more useful virtual files in the top-level of the /proc/ directory. 5.2.2. /proc/cmdline 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/hda2 This tells us that the kernel is mounted read-only (signified by (ro)) off of the second partition on the first IDE device (/dev/hda2).
