            Bug ID: 3437
           Summary: implement ssh’s -G for sftp and scp
           Product: Portable OpenSSH
           Version: v9.0p1
          Hardware: Other
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P5
         Component: Miscellaneous
          Assignee: unassigned-bugs at mindrot.org
          Reporter: calestyo at scientia.org


My understanding is that ssh’s -G option acts like a --dry-run (in the
sense that it can be used jointly with any other valid options to ssh)
+ printing out the settings.

As mentioned in #3436, this makes -G great for other programs to parse
ssh_config without having to deal with any format changes/extensions
there or with going through the Host/Match blocks.

It would be nice if the same option was added to sftp and scp.

Assuming one has an arbitrary sftp/scp command line (that one wants to
have parsed, with options from ssh_config), one cannot simply replace
sftp/scp with ssh, where -G already exists, because sftp/scp have
several options and other arguments that don't work with ssh.

So one would need to implement some command line parsing to adapt to
that and use ssh instead.

Much simpler would be if sftp/scp had the same options.
