How to recursively remove files with mpremote? #9802
-
|
I recently use mpremote instead of rshell and I like it, but I cannot find a good way to remove files from the device recursively (without supplying all the file paths manually). Has anyone any advice on how to do this with mpremote? There is a rm and a rmdir command but suppling -r argument is not supported and using |

I don't think that does what @saraverbeecke is asking -- this will non-recursively remove all files in a directory, but they're looking for recursive remove, as well as doing it from mpremote. |

Hi all, I would like to share my personal solution to the problem. I made this simple script that makes a full cleanup of all uploaded files. I then make a cleanup and a full upload of all files each time. If this is considered too drastic, the example can easily be tweaked to accomodate more sophisticated needs.
import os
DIRECTORY_MARKER = 32768
FILE_MARKER = 16384
def notify(*args: str) -> None:
print(*args) # noqa: T201
def join(path_a: str, path_b: str) -> str:
return f"{path_a}/{path_b}"
def list_files(base: str) -> list:
# micropython: -> ignore attr-defined
return [d[0] for d in os.ilistdir(base) if d[1] == FILE_MARKER] # type: ignore[attr-defined]
def list_directories(base: str) -> list:
# micropython: -> ignore attr-defined
return [d[0] for d in os.ilistdir(base) if d[1] == DIRECTORY_MARKER] # type: ignore[attr-defined]
def cleanup(base: str = ".") -> None:
notify(f"Cleaning up {base}")
for f in list_directories(base):
file_to_remove = join(base, f)
notify(f"removing file: {file_to_remove}")
os.remove(file_to_remove) # noqa: PTH107 (micropython)
for d in list_files(base):
dir_to_remove = join(base, d)
notify(f"removing dir: {dir_to_remove}")
cleanup(dir_to_remove)
os.rmdir(dir_to_remove) # noqa: PTH106 (micropython)
if __name__ == "__main__":
cleanup(".")Then, using
e.g. in my case:

You could consider using mpr. It merely wraps Of course this "trick" uses mpr's directory/path inference and exploits the wildcard file list generated by your shell to pass those local file names to the remote device. It assumes those same names exist in the analogous directory there. |

Ha! That's a tricky question... I've been working on a simple on-board solution...
(save as 'kill_ffs.py' on the root path of the device) It still has some issues with getting all the directories removed but you might be able to fix that... btw... it has code to skip the script itself and 'boot.py'. I think it would still work even if you still delete them. Hope this helps! |

If all you want to do is nuke the filesystem, then just reinitialising the filesystem might be easier. I do this a lot, so have an alias set up in mpremote to re-format the filesystem (with littlefs). See (Unfortunately it's slightly different on each port, the stm32, esp32/esp8266, and rp2 versions are there). |

Late follow-up here, but I just needed this exact thing and your aliases are super useful @jimmo - thanks! |

I think that may be my Powershell verb-action legacy shining through... Easier to fix on the filesystem than in the wetware ... |

@Josverl Getting this to work has proved to be a very useful learning exercise re the extensibility of mpremote. Unfortunately your repo seems to be set up to disallow the raising of issues, hence my response here. The following are the steps I needed to take to get this to work. FWIW I use Linux Mint 20.3 and Python 3.8.10. Firstly I cloned the repo into my home directory, with the result that I then hit a problem with this line in config.py because here = Path("/home/adminpete/mpremote_config/mpremote/config.py").parent.absolute()whereupon it worked. At the very least I should interrogate the environment variable, but maybe there's a better way? It would be nice to see these issues fixed, and some clear docs explaining how to install and use it, because it provides a very useful way to extend the capability of Getting back to the original post, the very useful $ mpr exec "folder='rats'" wipe_folderhowever it leaves the folder intact (but empty). I would expect it also to remove the folder (easily fixed). |

The repo started as a way to replicate my config across different machines, so had only the bare necessities The missing Without that I also needed a ugly hack similar to yours, or copy the location logic from mpremote (not pretty either) when i wrote the wipe_folder script I intended it to be run from the root. but agree is makes sense to try to delete the folder - but avoid erroring out if it is run from the root |
