SYSCTL.CONF(5)                  File Formats                  SYSCTL.CONF(5)

NAME         top

       sysctl.conf - sysctl preload/configuration file

DESCRIPTION         top

       sysctl.conf is a simple file containing sysctl values to be read in
       and set by sysctl.  The syntax is simply as follows:

              # comment
              ; comment

              token = value

       Note that blank lines are ignored, and whitespace before and after a
       token or value is ignored, although a value can contain whitespace
       within.  Lines which begin with a # or ; are considered comments and
       ignored.

NOTES         top

       As the /etc/sysctl.conf file is used to override default kernel
       parameter values, only a small number of parameters is predefined in
       the file.  Use /sbin/sysctl -a or follow sysctl(8) to list all
       possible parameters. The description of individual parameters can be
       found in the kernel documentation.

EXAMPLE         top

              # sysctl.conf sample
              #
                kernel.domainname = example.com
              ; this one has a space which will be written to the sysctl!
                kernel.modprobe = /sbin/mod probe
