What is your current rclone version (output from rclone version)?

rclone v1.69.0

What problem are you are trying to solve?

I have a remote sftp site configured.
I am trying to capture the output of lsjson to get the details of all the remote files so that i can work on a duplicate file not being transferred (fyi im attempting to replicate over 1 million files from another remote system).

I am using --log-file to capture the logs and --progress to see the status - which works perfect on its own, however the output of lsjson is output to the stdout so the only way of capturing that information is to redirect stdout to a file in the console.

How do you think rclone should be changed to solve that?

Is there a way of outputting the progress information to the console and still redirect the output of lsjson to stdout/file?
I can think of two possible solutions:

1. add something similar to --output-file to the ls* commands so that their output goes to the file but progress/errors still goes to stdout
2. add the ability to redirect progress to stderr, that way a redirect in the console still captures the ls file output but i can still see the command progress in the console window

This seems plausible.

2. add the ability to redirect progress to stderr, that way a redirect in the console still captures the ls file output but i can still see the command progress in the console window

That will interfere with rclone's logging system (--log-file) and would be mega complex. I don't want to do that (shudders).

@ukdocCT do you want to have a go at option 1 ?
