• Screen command

The biggest benefit of the screen command group is that when your shell exits or shuts down, the service you run does not matter, that is, we can open a set of services in screen without being affected by the disconnection of the terminal.

Screen-s Test          #创建一个名字为test的screenscreen-R test          #打开名字为test的screenscreen-R pid           #打开进程号为pid的screenscreen- LS              #列出所有的screenctrl + a,d              #当在一个screen时, exit Screenctrl + a,n              #当在一个screen时, switch to the next window Ctrl + A,c              # When in a screen, create a new window

• SCP command

SCP local_file [Email protected]_ip:remote_dir    #拷贝本地文件到远程机器上scp-R local_dir [email protected]_ip:remote_dir  #拷贝本地整个目录到远程机器上

• Package Installation Management Commands

Assuming that the package you want to install is called an app, note that commands here usually require sudo or root privileges.

CentOS system, Redhat system RPM-QA | grep app      #查找本机是否安装了app, Rpm-ivh app.rpm        #假设你有app的rpm包, installs sudo yum install app    #否则就在线安装yum Update app          #更新apprpm-e app              #删除已安装的app包//suse, openSUSE system Zypper Search app       #查找本机是否安装了app zypper install app      # Install the Zypper Update app       #更新zypper the Remove app       #删除zypper LR               #列出所有已定义的安装源.
