5.2.2.1 -ls list remote files
If the -ls option is given, no files are transferred; instead, remote files are listed. Only a hostname specification and optional remote file specification need be given. For example:
pscp -ls [email protected]:dir1
The SCP protocol does not contain within itself a means of listing files. If SCP is in use, this option therefore assumes that the server responds appropriately to the command ls -la; this may not work with all servers.
If SFTP is in use, this option should work with all servers.
