#pssh 远程批量执行命令 
pssh -h ip.txt -P "uptime" 
#-h  后面接主机ip文件,文件数据格式[user@]host[:port]
#-P  显示输出内容
#如果没办法密钥认证.可以采用下面方法,但不是很安全
sshpass -p abcd-1234 pssh -A -h ip.txt -i "uptime"
 
#pscp 并行传输文件到远端
#传文件,不支持远程新建目录
pscp -h ip.txt test.py /tmp/dir1/
#传目录
pscp -r -h ip.txt test/ /tmp/dir1/
 
#prsync 并行传输文件到远端
#传文件,支持远程新建目录,即目录不存在则新建
prsync -h ip.txt test.py /tmp/dir2/
#传目录
prsync -r -h ip.txt test/ /tmp/dir3/
 
#pslurp从远程拉取文件到本地,在本地自动创建目录名为远程主机ip的目录,将拉取的文件放在对应主机IP目录下

#拉取文件
pslurp -h ip.txt -L /root/ /root/1.jpg picture
