/proc 100%

The df/bdf command shows /proc 100% full all the time. What does /proc contain? and why 100% all the time even on a new setup.

"The /proc file system is only a "Virtual" file system. none of the files in /proc are really there-they're all, "pretend" files made up by the kernel to give you information about the system and don't take up any hard disk space. :slight_smile:

Many programs actually gather information from files in /proc(ie. ps, top). /proc is a good source of information about your hardware, Memory and Performance. Most of it is read-only, but some files allow kernel variables to be changed in real time.

Catting proc will let you see what is in a particular file of proc:
cat /proc/meminfo
cat /proc/cpuinfo

and the number directories in /proc are running process information by PID.
