#3 Overwrite existing files

[Stefan Lang]

When trying to overwrite an existing file on the NXT brick (e.g. a newer version of a .rxe file), linxt returns an error.

There should be an option to automagically or by command line option overwrite existing files or/and to delete files from the NYT brick.

This would be also #1 on my wish list.

philoware has posted a patch that works fine (see patches section). I think this should be added to the main code.

I have created a patch to enable linxt to delete a file on the brick. Apply the following patch to modify linxt.

Usage: linxt -delete filename.rxe

You may combine -delete and -upload in the same statement to replace an already existing file:
linxt -delete filename.rxe upload filename.rxe
