Tips on Using SFTP & SSH

For convenience, write *.expect scripts to log into SFTP and SSH automatically.

You need to install expect first. For example in Mac OS X, using

brew install expect

File login-sftp.expect:

#!/usr/bin/expect
set timeout 30
spawn sftp username@host-name
expect "*password: "
send "your-password\r"
expect "sftp> "
interact

File login-ssh.expect:

#!/usr/bin/expect
set timeout 30
spawn ssh username@host-name
expect "*password:"
send "your-password\r"
interact

To use these, just use command below in the Terminal (assuming $PATH_LOGIN is the directory where the expect scrips are):

expect $PATH_LOGIN/login-ssh.expect

or

expect $PATH_LOGIN/login-sftp.expect

Further more, we can use alias to make it more faster, add lines below in ./zshrc (since I use zsh):

alias login_ssh="expect $PATH_LOGIN/login-ssh.expect"
alias login_ssh="expect $PATH_LOGIN/login-ssh.expect"

Then type key esc and :wq to save it.

Then enter command below in Terminal:

source ./zshrc

Now you can use command login_ssh/login_sftp directly to connect to the remote host!
