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

Hi list,

I asked this question a few days ago on the perl-win32-users list but
still need some help. It seems what I need may not be possible.

I have a perl (5.6) SFTP client (Net::SFTP) that gets and puts files
using either a full or relative path with the filename something like
this:

$sftp->get( $remotename, $localname ); # where $remotename =
'/Home/OUT/myfile.txt'

But I have a remote system with a custom server app that rejects the
path and requires a chdir to the correct file location. To fetch a
file I need to do something like this:

$sftp->chdir( $path ); #cd to the OUT folder
$sftp->get( $shortname, $localname); # get the file using only the
file name

I see no way to do $sftp->chdir. Please advise if something similar is
possible. I have tried many combinations of commands using SSH such as
$ssh->cmd( 'cd $path' ) with no joy. $ssh->cmd() always seems to hang.
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
