OS X’s scutil

Posted by | Posted in Bash, Code, Command-Line, OS X | Posted on 17-07-2009

scutil is OS X’s way of managing system configuration parameters. These parameters not only include HostName, ComputerName, LocalHostName, but basically anything that the configd daemon uses.

Most of those files are located in


To enter the scutil prompt, type


To view all the scutil commands, type

> help

To get a list of all the scutil keys, type “list” or “list + [Pattern]”

> list

To view the contents of a key, type “show + [Pattern”

> show Setup:/Network/Global/IPv4

This will result in a pattern like this.

< dictionary > {
  ServiceOrder :  {
    0 : 59267386-49A6-401F-A23E-BE372AD748EB
    1 : 68719F97-53F0-479E-A497-8A3B809728D1
    2 : E936454A-40CA-4867-A759-61D6C38F5972

To get your computer name, local host name or host name type,

/usr/sbin/scutil --get ComputerName
/usr/sbin/scutil --get LocalHostName
/usr/sbin/scutil --get HostName

And setting those names are just as easy.

/usr/sbin/scutil --set ComputerName NEWNAME
/usr/sbin/scutil --set LocalHostName NEWNAME
/usr/sbin/scutil --set HostName NEWNAME

On a side note. ComputerName HostName can be set to blank, but LocalHostName needs at least 1 character.

To quit scutil type,

> quit

Family Commands of scutil are

/usr/sbin/scutil  -- Manage system configuration parameters
/usr/sbin/scselect  -- Select system configuration "location"
/usr/sbin/configd -- -- System Configuration Daemon
