判断当前用户是否是root ,代码如下:
#---------------------------- root user check ---------------------start
if [ `id -u` -ne 0 ] then
echo "Please re-run ${this_file} as root."
exit 1
fi
#---------------------------- root user check ---------------------end
if [ x"$USER" = x"" ]then
if id |grep "^uid=0(root)">/dev/null then
:
else
echo "Please rerun `basename $0` as root ."
exit 1
fi
else
if [ ! x"$USER" = x"root" ]then
echo "Please rerun `basename $0` as root ."
exit 1
fi
fi
#=============== check current user start ================
if [ ! $USER = root ]then
echo "Please rerun this script as root ."
exit 1
fi
#=============== check current user end ================
#!/bin/sh
if id |grep "^uid=0(root)">/dev/null then
echo is root
else
echo not root
fi
check_user(){
if [ $UID -ne 0 ]then
echo "Current user is not ROOT."
echo "Please rerun the installer as Root user."
exit 11
fi
}
普通用户
下图箭头指向为 $
命令 : userdel -r ztac
注:如果没有加 -r ,并不能删除该用户的所有信息,只是删除了 /etc/passwd 、 /etc/shadow 、 /etc/group/ 、 /etc/gshadow 四个文件里的该账户和组的信息。使用 find / -name "*ztac*" 查看后发现还有内容,但是使用 -r 的话,查不到内容。
