Linux用户管理系统(代码+答辩+论文)
功能需求：（1）单个用户添加：通过键盘输入用户名和口令，用户组的指定可选（若输入则将用户归于该组，否则用系统默认处理），要求首先检查新用户是否存在，并给出相应信息；（2）批量添加：待建用户信息保存在文件中，包括用户名、口令、用户描述及所属组（格式自定）（3）单用户删除：用户名通过键盘输入同时删除用户主目录，删除用户前将用户名主目录中的内容备份到特定目录中，命名格式：用户名.tar.gz（4）批量删除：用户名通过文件提供，要求同单用户删除。（5）用户配额：对指定用户的用户主目录启用磁盘配额。注：为用户设定3种配额模板：①100M空间，200个i节点；②200M空间，400个i节点；③500M空间，1000个i节点。(1)利用read命令从命令行输入用户名存入变量; []或test进行条件的判断； Cut命令剪切文件列，配合grep命令剪切文件行，从而获取文件中特定信息； Useradd命令，-g指定组，-m生成用户主目录； Passwd命令用户改用户口令；(2)tar命令压缩文档，后缀.tar.gz要自己加上； Mv移动文件到特色目录下； Usedel删除用户，参数-r同时删除用户主目录；(3)while read可以逐行读取文件内容； >进行输出重定向，并且覆盖输出内容到文件； Chpasswd成组更改用户口令，文件行格式为“用户名:口令”；(4)跟单个用户删除操作一样，只是从文件读取要删除的用户名(5)给用户进行配额前需要给相应目录开启配额功能； Disk –l查询可进行配额的磁盘分区信息； Vi /etc/fstab文件，添加usrquota开启用户配额权限，添加grpquota开启组配额权限，文件中同行各字段间用tab键隔开； Mount –o remount /重新挂载文件系统，让fstab文件生效； Quotaon /开启配额功能； Setquota命令进行用户配额的设置；(6)while touch循环生成多个文件检查i节点的配额设置情况；测试前需要给相关用户对/目录的写权限； dd if=/dev/zero of=$username bs=1M count=500给相关用户写数据，测试用户可用空间的配额设置情况；
