uploading files from "bash" to 7.18's /ip/cloud/file-share feature using `curl`
Posted: Fri Feb 07, 2025 6:00 pm
I've giving the new "file-share" a try in the 7.18 beta. It's working pretty, outside minor kinks, and /ip/cloud/file-share likely have a lot of useful applications.
It should be noted file-share does supports uploading files too, which you can do from the web page at the "File Sharing URL" for a specific /ip/cloud/file-share. I check the "Allow Uploads" box and it works.
It was not clear how to do this with curl. Inspecting the browser, it's using standard POST form encoding using multipart/form-data. So in curl from a desktop you can copy a file name "example.txt" using the following command:
The only real trick is a CURL thing, but the URL must have a trailing / on the end of it. Otherwise it may not work with how processes the -F. If you cut-and-paste from RouterOS, you'll need to add a / at the end of the "File Direct Url" from winbox.
If you want to copy a set of files, I wrote a quick-and-dirty bourne shell (ash, bash, zsh) function, copy2router(). It will take 1 or files to copy from shell prompt and use "curl" with a /ip/cloud/file-share. Importantly the shell will expect the wildcard like *.txt or *.* or *, all those should work. It use an environment variable ICRS_URL="https://...." which must be set to use the function, and the URL should be without any trailing slash, to match shown in RouterOS (the function below will ADD the / for you - so it's still needed want envvar to match what RouterOS showed).
Now I'm not sure what happen when files are "big",/slow connections, etc... but the curl command to copy MULTIPLE FILES to try is here:
Some of this may change since 7.18 is in beta, but at least I'm ahead of some future "how to use file-share with curl" questions
