RedHat 9 (Linux i386) - man page for sysctl (redhat section 8)

SYSCTL(8)										SYSCTL(8)

NAME
       sysctl - configure kernel parameters at runtime

SYNOPSIS
       sysctl [-n] [-e] variable ...
       sysctl [-n] [-e] -w variable=value ...
       sysctl [-n] [-e] -p <filename>	 (default /etc/sysctl.conf)
       sysctl [-n] [-e] -a
       sysctl [-n] [-e] -A

DESCRIPTION
       sysctl is used to modify kernel parameters at runtime.  The parameters available are those
       listed under /proc/sys/.  Procfs is required for sysctl(8) support in Linux.  You can  use
       sysctl(8) to both read and write sysctl data.

PARAMETERS
       variable
	      The name of a key to read from.  An example is kernel.ostype.  The '/' separator is
	      also accepted in place of a '.'.

       variable=value
	      To set a key, use the form variable=value, where variable is the key and	value  is
	      the  value  to  set  it  to.   If the value contains quotes or characters which are
	      parsed by the shell, you may need to enclose the	value  in  double  quotes.   This
	      requires the -w parameter to use.

       -n     Use this option to disable printing of the key name when printing values.

       -e     Use this option to ignore errors about unknown keys.

       -w     Use this option when you want to change a sysctl setting.

       -p     Load in sysctl settings from the file specified or /etc/sysctl.conf if none given.

       -a     Display all values currently available.

       -A     Display all values currently available in table form.

EXAMPLES
       /sbin/sysctl -a

       /sbin/sysctl -n kernel.hostname

       /sbin/sysctl -w kernel.domainname="example.com"

       /sbin/sysctl -p /etc/sysctl.conf

FILES
       /proc/sys /etc/sysctl.conf

SEE ALSO
       sysctl.conf(5)

BUGS
       The -A parameter behaves just as -a does.
