如何从命令行删除 Mac OS X Snow Leopard 用户帐户？

我需要创建一个脚本来从命令行自动删除 Mac OS X 用户，而不是从 GUI，只是在终端中，但我还没有找到如何在 Snow Leopard 中执行此操作。

您想使用该程序dscl来管理 Mac OS X 上的用户。Mac OS X 使用它自己的目录来管理用户和组，因此管理用户和组的实用程序是 Mac OS X 独有的。

删除用户需要几个步骤：

  1. 用户的文件夹/文件，一个相当标准的rm可以删除他们的用户文件夹默认在/Users/
  2. 用户在群组中的成员身份。
  3. 用户的主要组
  4. 最后，用户的实际账户及其密码哈希。

犹他大学 Mac 管理员小组提交了一份出色的脚本代码片段它可以完成您需要的所有检查和工作。

#!/bin/bash

if [[ "$(/usr/bin/whoami)" != "root" ]]; then printf '\nMust be run as root!\n\n'; exit 1; fi

declare sudo=/usr/bin/sudo

printf "\e[1mDelete user account\e[m: "

if [[ -z "$user" ]]; then printf '\nNo user specified! Please, try again!\n\n'; exit 1; fi

# make sure the user exists
usertest="$(/usr/bin/dscl . -search /Users name "$user" 2>/dev/null)"

if [[ -z "$usertest" ]]; then printf "\nUser does not exist: $user\n\n"; exit 1; fi 


# get user's group memberships
groups_of_user="$(/usr/bin/id -Gn $user)"

if [[ $? -eq 0 ]] && [[ -n "$(/usr/bin/dscl . -search /Groups GroupMembership "$user")" ]]; then 
   # delete the user's group memberships
   for group in $groups_of_user; do
      $sudo /usr/bin/dscl . -delete "/Groups/$group"  GroupMembership "$user"
      #$sudo /usr/sbin/dseditgroup -o edit -d "$user" -t user "$group"

fi


# delete the user's primary group
if [[ -n "$(/usr/bin/dscl . -search /Groups name "$user")" ]]; then
   $sudo /usr/sbin/dseditgroup -o delete "$user"

# if the user's primary group has not been deleted ...

printf "

# find the GeneratedUID of the user and remove the password hash file

# delete the user
$sudo /usr/bin/dscl . -delete "/Users/$user"
