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

NAME
sysctl.conf - sysctl preload/configuration file DESCRIPTION
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. EXAMPLE
# sysctl.conf sample # kernel.domainname = example.com ; this one has a space which will be written to the sysctl! kernel.modprobe = /sbin/mod probe FILES
/run/sysctl.d/*.conf /etc/sysctl.d/*.conf /usr/local/lib/sysctl.d/*.conf /usr/lib/sysctl.d/*.conf /lib/sysctl.d/*.conf /etc/sysctl.conf The paths where sysctl preload files usually exist. See also sysctl option --system. SEE ALSO
