How do I add a group in Mac OS X 10.6?

Surprisingly, it's been tough for me to find the command(s) to do this. Does anyone know how to add a group? Thanks!

Or do something like this:

# create the MySQL group
dscl . create /Groups/mysql
# give it some group id
dscl . create /Groups/mysql gid 296

From serverfault Tony

• I've used these to add dba group:

  sudo dscl . -create /groups/dba
  sudo dscl . -append /groups/dba gid 4200
  sudo dscl . -append /groups/dba passwd "*"
  

  From Andrea Girardi

• "System preferences" -> "Accounts" -> "+" (as if you were adding new account) -> Under "New account" select "Group" -> Type in group name -> "Create group"

• pulegium's answer is generally preferred, but if you want a command-line way:

  sudo dseditgroup -o create mysql
  

  (note that creating a group named mysql is probably a bad idea -- there's already a group named _mysql, with mysql as an alias.)

  From Gordon Davisson

• As Gordon Davisson notes, standard Mac OS X 10.6 already has a mysql group, as this command shows:

  dscl . -read /Groups/mysql
  

  You shouldn’t create your own mysql group, and any attempts to modify it will affect the _mysql group. But to answer your question, the most succinct way to do it would be this single command:

  dscl . -create /Groups/mysql gid 296
  

  To add an encrypted password to the group:

  dscl . -passwd /Users/mysql ‘my secret’
  

  Note: Andrea Girardi’s method creates a plaintext password, which isn’t so good.
