通过Xshell上传文件

在对服务器进行维护的时候，我们经常需要进行传文件，这里介绍一个WINDOWS与LINUX进行文件互传的方法——使用lrzsz传输

实现说明：lrzsz不适合传输大文件，只适合传输代码级别的小文件

Windows端已经安装Xshell，通过Xshell使用ssh登陆远端的Linux服务器，首先查看是否已经安装lrzsz

#输入
rpm -qa lrzsz

无输出表示未安装，接下来输入命令安装：

#Ubuntu系列
sudo apt-get install lrzsz
#Centos系列
sudo yum -y install lrzsz
#注：-y表示默认Yes，可以去掉-y

1.上传文件（Windows到Linux）

之后输入rz –help查看命令提示

[root@VM_0_7_centos html]# rz --help

直接输入命令：rz即可从Windows上传文件到Linux中

rz
#或者需要覆盖的话rz -y

2.下载文件（Linux到Windows）

输入 sz <文件名> 即可直接从Linux下载文件下来，注意直接输入文件名是当前路径，也可以输入绝对路径进行传输

sz

输入sz –help查看命令细则
