proc_sys(5)                File Formats Manual               proc_sys(5)

NAME         top

       /proc/sys/ - system information, and sysctl pseudo-filesystem

DESCRIPTION         top

              This directory (present since Linux 1.3.57) contains a
              number of files and subdirectories corresponding to kernel
              variables.  These variables can be read and in some cases
              modified using the /proc filesystem, and the (deprecated)
              sysctl(2) system call.

              String values may be terminated by either '\0' or '\n'.

              Integer and long values may be written either in decimal
              or in hexadecimal notation (e.g., 0x3FFF).  When writing
              multiple integer or long values, these may be separated by
              any of the following whitespace characters: ' ', '\t', or
              '\n'.  Using other separators leads to the error EINVAL.
