do
sshpass -p $password ssh root@172.1x.1x.$num -o StrictHostKeyChecking=no "mkdir /tmp/sb"
done

3.用法介绍

-p password #后跟密码
[root@zhu ~]# sshpass -p 123456 ssh root@192.168.56.102

[root@jiang ~]# exit
logout

-f filename #后跟保存密码的文件名，密码是文件内容的第一行。
[root@zhu ~]# cat 1.txt
123456
[root@zhu ~]# sshpass -f 1.txt ssh root@192.168.56.102

[root@jiang ~]# exit
logout

-e #将环境变量SSHPASS作为密码
[root@zhu ~]# export SSHPASS=123456
[root@zhu ~]# sshpass -e ssh root@192.168.56.102

#从命令行方式传递密码 -p指定密码
$ sshpass -p '123456' ssh user_name@host_ip
$ sshpass -p '123456' scp root@host_ip:/home/test/t ./tmp/

如在多台主机执行命令：

[root@zhu ~]# cat a.sh
#!/bin/bash
for i in $(cat /root/1.txt)
do
echo $i
sshpass -p123456 ssh root@$i 'ls -l'
done
