Transferring files via SFTP

Linux

The Linux sftp command does not provide an argument to specify a password. If you do not want to configure keys for the transfer, you can install the sshpass program.

Complete!

Once sshpass is installed, you can call sshpass, pass the password and then pass the sftp command string as an argument.

To specify multiple command strings you can either pass a file fill of commands, or you can use the bash here-string syntax.

sshpass -p "password" sftp -v user@server.tapetrack.com <<< $'cd upload\n put drm.csv\n ls -al'
