How to transfer a file using sftp on UNIX

I want to transfer the .png file from a directory on my computer to a directory on a remote server.

I need to use SFTP to protect the file and transfer mode. And I already have a UNIX script file (.ksh) for copying files normally. How to implement SFTP transmission?

Use sftpinstead of any command you use in your .ksh script. See sftp man for help.

You can also see scpsecure copy - scp man .

EDIT

sftp mainly for interactive operations, you need to specify the host with which you want to connect:

sftp example.com

, .

, scp :

scp /path/to/localfile user@host:/path/to/dest

.

spawn sftp -b batch-file user@host
