RE: How to chdir using SFTP or SSH on Win32

Hi Rob,

Yeah, I got all that but unfortunately I need a workaround due to a coding
error on the server end. The server-end SFTP logic is a rewrite of an
earlier FTP app that still expects a CD before the GET. Any ideas? Magic?

Thanks,
Sturdy

TIA.

SSH doesn't support a cwd command - it is the job of the client to keep
track of where it is in the remote directory structure. You can establish
the path to your login directory by executing

  $sftp->do_realpath('.');

and after that you can specify either a path relative to that login
directory or an absolute path. The location of '.' never changes.

HTH,

Rob
