作业
1、要求添加一个用户newuser,如果其已经存在则显示”The user USERNAME is exists”,如果存在,则添加之,并将其密码设置为”[email protected]”
#!/bin/bash
#
username=newuser1
if ! id $username &> /dev/null;
then adduser $username
echo $username | passwd --stdin "[email protected]" &> /dev/null
echo "Add user $username sucessfully."
else "The user is exists."
fi
exit
2、写一个脚本,如果某路径不存在,则将其创建为目录,否则显示其存在,并显示内容类型
#!/bin/bash
#
path="/tmp/testdir"
if [ ! -e $path ];then
if [ ! -d $path ];then
mkdir $path
echo "Make directory $path sucessfully."
else echo "$path has been exists."
fi
else echo "$path has been exists."
fi
