!! docker compose is required for this exercise

Write a script with any language to move all files in sftp server sftp1 to sftp2 root dir. The original file shall be removed from sftp1 and placed at root dir(/home/bar) of sftp2

Initial the environment by running ./start.sh

$ ./start.sh

It will spining up SFTP servers sftp1 and sftp2, generate random file structure in directory sftp1. Below is an example file structure

/sftp1
└── depth1
    ├── 1-1.txt
    └── depth2
        ├── 2-1.txt
        ├── 2-2.txt
        ├── 2-3.txt
        ├── 2-4.txt
        └── depth3
            ├── 3-1.txt
            ├── 3-2.txt
            ├── 3-3.txt
            ├── 3-4.txt
            └── depth4
                └── 4-1.txt

To troubleshoot, you can connect sftp1 with below command, with password pass

sftp -o NoHostAuthenticationForLocalhost=yes -P 2222 foo@localhost

and sftp2

sftp -o NoHostAuthenticationForLocalhost=yes -P 2223 bar@localhost

To restart the environment, it will generate new random file structure in sftp1 and spin up new sftp servers

./restart.sh

Good Luck
