The Process File System (PROCFS) resides in memory. It contains a list of active processes, by process number, in the /proc directory. Information in the /proc directory is used by commands like ps. Debuggers and other development tools can also access the address space of the processes by using file system calls.
Do not delete the files in the /proc directory. Deleting processes from the /proc directory will not kill them. Remember, /proc files do not use disk space, so there is little reason to delete files from this directory.
The /proc directory does not require system administration.
