如何向scp传递密码？

ssh-keygen -t rsa

ssh-copy-id user@remote_host

scp local_file user@remote_host:/path/to/remote_directory

sudo apt-get install sshpass  # Debian/Ubuntu
sudo yum install sshpass      # CentOS/RHEL

sshpass -p 'your_password' scp local_file user@remote_host:/path/to/remote_directory

sudo apt-get install expect  # Debian/Ubuntu
sudo yum install expect      # CentOS/R甘草

#!/usr/bin/expect -f

set timeout -1
set user [lindex $argv 0]
set password [lindex $argv 1]
set local_file [lindex $argv 2]
set remote_host [lindex $argv 3]
set remote_directory [lindex $argv 4]

spawn scp $local_file $user@$remote_host:$remote_directory
expect "password:"
send "$password\r"
expect eof

chmod +x scp_with_password.exp
./scp_with_password.exp user password local_file remote_host remote_directory
