proc_sys(5) File Formats Manual proc_sys(5)
NAME
/proc/sys/ - system information, and sysctl pseudo-filesystem
DESCRIPTION
/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) 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 inte-
ger or long values, these may be separated by any of the follow-
ing whitespace characters: ' ', '\t', or '\n'. Using other sepa-
rators leads to the error EINVAL.
