Debian deluser命令在脚本中的自动化应用

deluser 命令用于从 Debian 系统中删除用户及其相关文件

1. 删除用户：

#!/bin/bash

# 检查参数数量
if [ "$#" -ne 1 ]; then
    echo "Usage: $0 <username>"
    exit 1
fi

# 变量赋值
USERNAME=$1

# 删除用户
deluser --remove-home $USERNAME

# 检查命令执行结果
if [ $? -eq 0 ]; then
    echo "User $USERNAME has been removed successfully."
else
    echo "Error: Failed to remove user $USERNAME."
fi

2. 删除用户组：

#!/bin/bash

# 检查参数数量
if [ "$#" -ne 1 ]; then
    echo "Usage: $0 <groupname>"
    exit 1
fi

# 变量赋值
GROUPNAME=$1

# 删除用户组
deluser --remove-group $GROUPNAME

# 检查命令执行结果
if [ $? -eq 0 ]; then
    echo "Group $GROUPNAME has been removed successfully."
else
    echo "Error: Failed to remove group $GROUPNAME."
fi

3. 同时删除用户和用户组：

#!/bin/bash

# 检查参数数量
if [ "$#" -ne 1 ]; then
    echo "Usage: $0 <username>"
    exit 1
fi

# 变量赋值
USERNAME=$1

# 删除用户及其主目录
deluser --remove-home $USERNAME

# 检查命令执行结果
if [ $? -eq 0 ]; then
    echo "User $USERNAME and its primary group have been removed successfully."
else
    echo "Error: Failed to remove user $USERNAME and its primary group."
fi

将上述脚本保存为文件（例如：remove_user.sh），并使用 chmod +x remove_user.sh 命令使其可执行。然后通过 ./remove_user.sh <username> 或 ./remove_user.sh <groupname> 命令运行脚本。请注意，您需要具有 root 权限才能成功执行这些脚本。
