sysctl.conf − sysctl(8) preload/configuration file
sysctl.conf is a simple file containing sysctl values to be read in and set by sysctl(8). 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.
# sysctl.conf
sample
#
kernel.domainname
= example.com
; this one has a space which will be written to the sysctl!
kernel.modprobe = /sbin/mod probe
