       sysv-rc-conf - Run-level configuration for SysV like init script links


       sysv-rc-conf [ options ]

       sysv-rc-conf  --list  [ service ]

       sysv-rc-conf [ --level levels ] service <on|off>


       sysv-rc-conf gives an easy to use interface for managing "/etc/rc{runlevel}.d/" symlinks.
       The interface comes in two different flavors, one that simply allows turning services on
       or off and another that allows for more fine tuned management of the symlinks. It's a
       replacement for programs like ntsysv(8) or rcconf(8).

       sysv-rc-conf can also be used at the command line when the desired changes to the symlinks
       are already known. The syntax is borrowed from chkconfig(8), although it does not follow
       it exactly.


       -c DIRECTORY, --cache=DIRECTORY
           The directory where the priority numbers, old runlevel configuration, etc.  should be
           stored. This defaults to "/var/lib/sysv-rc-conf". See the FILES section below and the
           --Purge option.

       -r DIRECTORY, --root=DIRECTORY
           The root directory to use. This defaults to "/". This comes in handy if the root file
           system is mounted somewhere else, such as when using a rescue disk.

       -P, --Purge
           Purge the information stored in the cache file. See the FILES section below and the
           --cache option.

       -v FILE, --verbose=FILE
           Print verbose information to "FILE"

       -V, --Version
           Print version information to STDOUT and exit


       -o [ see description ], --order=[ see description ]
           Allows various sorting orders and ways to display the rows. The argument can be made
           up of any of the following:

           a   Sort the rows alphabetically. This is the default if the -o option isn't

           n   Show the priority numbers along with the name of the service.

           p   Sorts by the priority numbers.

               level can be any runlevel, 0-9 or S. This controls which runlevel the priority
               numbers are sorted at. It only makes sense to use this in conjuntion with p. If
               omitted the priority numbers are sorted by the current runlevel the system is in.

       -p, --priority
           Alternate layout. Instead of just showing a checkbox, the priority of the service and
           the S or K are allowed to be edited. This is for more fine tuned control then the
           default layout allows.

       -s levels, --show=levels
           Which runlevels to show. This defaults to up to 8 of the runlevels available on the
           system. Usually this means it will show 1, 2, 3, 4, 5, 0, 6, and S.  The syntax calls
           for the runlevels to be allruntogether. For instance, to show runlevels 3, 4, and 5
           the syntax would be "--show=345". Also see --order.


       --level levels
           The runlevels this operation will affect. levels can be any number from 0-9 or S. For
           example, --level 135 will affect runlevels 1, 3, and 5.  If --level is not set, the
           default is to affect runlevels 2, 3, 4, and 5.  This option is only used for the
           command line interface, see the section below labled USING THE CLI for more

       --list [name]
           This option will list all of the services and if they are stopped or started when
           entering each runlevel. If name is specified, only the information for that service is



       When using either GUI layout described below, all configuration changes to the symlinks
       will happen immediately, not when the program exits.

       Using the Default layout

       The default (simple) layout shows in a grid fashion all of the services that are in
       "init.d" and which runlevels they are turned on at. For example, where the "ssh" row and 3
       column intersect, if there is an 'X' in the box there that means the ssh service will be
       turned on when entering runlevel 3. If there is no checkbox it can mean that either there
       are no links to the service in that specific runlevel, or that the service is turned off
       when entering that runlevel. If more configuration detail is needed, see the next
       paragraph and the --priority option.

       Using the Priority layout

       The priority (advanced) layout also uses a grid fashion, but instead of checkboxes there
       are text boxes that can have a few different values. If the text box is blank, that means
       there isn't a symlink in that runlevel for that service. This means that when changing
       into that runlevel that the service will not be started or stopped, which is significant.
       If the text box starts with the letter K that means that the service will be stopped when
       entering that runlevel. If the text box starts with the letter S that means the service
       will be started when entering that runlevel. The two digits following is the order in
       which the services are started. That means that "S08iptables" would start before "S20ssh".
       For more information see your system documentation.


       To move around use the arrow keys, or if the terminal support it, the mouse.  Typically
       there is more then one page of services (unless the terminal screen is large), to move
       between the pages use CTRL-n or CTRL-p, or simply arrow key down or up at the bottom or
       top of the screen, respectively. The bottom of the screen also shows these movement
       commands for quick reference. To restore the symlinks back to their original state before
       the sysv-rc-conf was run, press the r key.  The h key will display a quick reference help

       Default layout

       When using the default layout use the space bar to toggle the service on / off.  An 'X' in
       the checkbox indicates that the service is on.

       Priority layout

       The priority layout uses the default movement keys. In order to edit the fields you can
       use CTRL-d to delete the character in front of the cursor or backspace to backspace. Use
       CTRL-b or CTRL-f to move the cursor backwards or forwards within the field. Note that only
       S, K, or any digit is allowed to be entered into the field.

       Starting / Stopping Services

       To start a service now, press the "+" or "=" key.  To stop  a service now, press the "-"

       This will call "/etc/init.d/service start" or "/etc/init.d/service stop".


       If the desired modifications to the symlinks are known and only one quick change is
       needed, then you can use a CLI interface to sysv-rc-conf.  Examples:

         # sysv-rc-conf --level 35 ssh off
         # sysv-rc-conf atd on

       The first example will turn ssh off on levels 3 and 5. The second example turns atd on for
       runlevels 2, 3, 4, and 5.


       Note: Feel free to skip this section

       sysv-rc-conf stores a cache of all the symlink information from "/etc/rc{runlevel}.d/" in
       "/var/lib/sysv-rc-conf/services" (See the --cache option to change the location of this
       file). It uses this cache to make an intelligent decision on what priority number to give
       the K or S link when they are changed in the simple layout. This cache is updated/created
       everytime the program is launched. The program needs to run with root privileges in order
       to update the cache. The format of the file is as follows:


       Here's a few examples:

         2 K 74 ntpd
         2 K 50 xinetd
         3 S 08 iptables
         3 S 80 sendmail

       sysv-rc-conf will first see if it can get an exact match from the cache.  For example, if
       the symlink for "cron" in runlevel 3 is S89cron and you uncheck it, sysv-rc-conf will
       first see if there is an entry in the cache that looks like "3 K nn cron", if so it will
       use nn for the priority number.

       If there wasn't a match, sysv-rc-conf will then see if there is another S or K (whichever
       you're switching to, so in this example, K) entry on a different runlevel - so an entry
       like "i K nn cron", where i is any runlevel. If found, the link will use nn.

       If there still wasn't a match, sysv-rc-conf will look for the opposite of S or K in any
       run level, and use 100 - that priority. So in our example, "i S nn cron". If nn is 20,
       then it will use 80 (100 - 20), since that is typically the way that the priority numbers
       are used.

       If there still isn't a match, the default priority of 20 for S links is used, and the
       default priority of 80 for K links is used.


       sysv-rc-conf should work on any Unix like system that manages services when changing
       runlevels by using symlinks in "/etc/rc{runlevel}.d/". Refer to your system documentation
       to see if that's the case (usually there's a "/etc/init.d/README").


       sysv-rc-conf only manages the symlinks in the "rc{runlevel}.d" directories. It's possible
       that packages may have other ways of being disabled or enabled.

       Because Curses takes over the screen sometimes error messages won't be seen on the
       terminal. If you run across any weird problems try redirecting STDERR to a file when you
       execute the program.

       For example:
         # sysv-rc-conf 2> err.out
