    Command:

    sysctl

    
    
    

    SYNOPSIS

           sysctl [-n] [-e] variable ...
           sysctl [-n] [-e] [-q] -w variable=value ...
           sysctl [-n] [-e] [-q] -p [filename]...
           sysctl [-n] [-e] [-q] --system
           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 print-
                  ing 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(s)  specified  or
                  /etc/sysctl.conf if none given.  Specifying - as filename  means
                  reading data from standard input.
    
           --system
                  Load settings from all system configuration 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
    
           -a     Display all values currently available.
           settings (example: sunrpc.* settings are  overridden  when  the  sunrpc
           module  is  loaded). This may cause some confusion during boot when the
           settings in sysctl.conf may be overriden. To prevent such a  situation,
           sysctl  must  be  run after the particular module is loaded (e.g., from
           /etc/rc.d/rc.local or by using the install directive in modprobe.conf)
    
    
    

    FILES

           /proc/sys /etc/sysctl.conf
