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 ker
nel.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 -p /etc/sysctl.conf
FILES
/proc/sys /etc/sysctl.conf
SEE ALSO
sysctl.conf(5)
BUGS
The -A parameter behaves just as -a does.
