How to update a forked GitHub repo.

# Add the remote, call it "upstream":

git remote add upstream

# Fetch all the branches of that remote into remote-tracking branches,
# such as upstream/master:

git fetch upstream

# Make sure that you're on your master branch:

git checkout master

# Rewrite your master branch so that any commits of yours that
# aren't already in upstream/master are replayed on top of that
# other branch:

git rebase upstream/master

# And finally push your local updated copy to GitHub:

git push



Upload files with curl.

Like this:

curl -F ‘data=@path/to/local/file’ UPLOAD_ADDRESS

Dus om /home/Cellie/test.txt te uploaden naar gebruik je:

 curl -F ‘data=@/home/Cellie/test.txt’ 

Met username / password  inlog word dat:

 curl --user admin:esp32 -F 'data=@/home/Cellie/test.txt'
