    NAME

    sysctl - configure kernel parameters at runtime
     
    

    SYNOPSIS

    sysctl [-n] [-e] variable ...
    sysctl [-n] [-e] [-q] -w variable=value ...
    sysctl [-n] [-e] [-q] -p <filename>
    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.
    -N
    Use this option to only print the names. It may be useful with shells that have programmable completion.
    -q
    Use this option to not display the values set to stdout.
    -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. Specifying - as filename means reading data from standard input.
    -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.
