1）使用for循环在/westos目录下批量创建10个html文件，其中每个文件需要包含10个随机小写字母加固定字符串westos
#!/bin/bash Path=/westos [ -d "$Path" ] || mkdir -p $Path for i in `seq 10` do random=$(openssl rand -base64 40 | sed 's/[^a-z]//g' | cut -c 3-12) touch $Path/${random}_westos.html done2） 创建10个用户westos（01-10），并设置其密码为10位随机数
[root@server tmp]# cat random.sh #!/bin/bash . /etc/init.d/functions user="westos" passfile="/tmp/user.log" for num in `seq -w 10` do pass="`echo $RANDOM | md5sum | cut -c 3-12`" useradd $user$num &> /dev/null && { echo "$pass" | passwd --stdin $user$num &> /dev/null echo -e "user:$user$num\tpasswd:$pass" >> $passfile } if [ $? -eq 0 ];then action "$user$num is ok" /bin/true else action "$user$num is failed" /bin/false fi done [root@server tmp]# sh random.sh westos01 is ok [ OK ] westos02 is ok [ OK ] westos03 is ok [ OK ] westos04 is ok [ OK ] westos05 is ok [ OK ] westos06 is ok [ OK ] westos07 is ok [ OK ] westos08 is ok [ OK ] westos09 is ok [ OK ] westos10 is ok [ OK ] [root@server tmp]# cat /tmp/user.log user:westos01 passwd:7fdb143dd9 user:westos02 passwd:6476ef99ad user:westos03 passwd:3962f843f4 user:westos04 passwd:feb2f5d496 user:westos05 passwd:7890eeabcf user:westos06 passwd:fa10a849f4 user:westos07 passwd:a740ee29f3 user:westos08 passwd:87e0eb374c user:westos09 passwd:293d9243f0 user:westos10 passwd:878c4df9f4
