Which commands are implemented in the SFTP library

Hi,
I want to use this library to update a library of images in multiple remote raspberry pis. Can you tell which commands are implemented? In particular, can I write files from the local machine to a remote machines.

Thanks
Michael

Taking a quick look at the example sketch:

…and at the source:

It lists:

quit, exit, pwd, ls, get, version, help

Seems like you want to implement a library method:

if(cmds[0].equals("put")) {
  // ...
}
