SCP Upload to a Specific Remote Directory

See more SCP Examples

Demonstrates how to upload a file using the SCP protocol (Secure Copy Protocol over SSH). The file is uploaded to a specific remote directory. It can be either a path relative to the HOME directory of the SSH user account, or an absolute path on the remote filesystem. Obviously, in both cases the SSH user account must have permission to create or overwrite a file in the specified directory. Tcl
