NAME top

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

DESCRIPTION top

   _/proc/sys/_
          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)](../man2/sysctl.2.html) 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**.
