Remote Linux Command

I have to work on Linux Server remotely these days. So I would like to take this as a note of commands on manipulating remote files.

ssh command

shell to login remote machine without entering password

set user abc123
set host 192.168.0.2
set password [your password]
set timeout -1

spawn ssh $user@$host
expect "*assword:*"
send "$password\r"
interact
expect eof

scp command

your user name is abc123 and you want to copy file this.md from your desktop to your remote machine 192.168.0.2.

upload files:

scp ~/Desktop/this.md abc123@192.168.0.2:/assignment1 this command will copy your file this.md to the direction /assignment1.

download files:

scp -r root@192.168.0.2：~/Desktop/files this command will copy all files from your remote machine to your /files direction on your desktop.

ftp command

to be continue…
