thanks sir

Adding that I stumbled across this, now about a year later while trying to figure out how to create a small json file via api, and after reading many many blogs & stackoverflow posts, this gist provided me the solution: the escaping of the quotes inside the data block. Thank you @aborruso! Here is my working example for those trying to base64 encode a small json snippet & curl PUT at the same time. It could be combined into a one-liner. Of course, your token has to have perms.

content=$(echo '{
   "repo":"my_repo",
   "is_production":"true",
   "maintainer":{
      "slack_channel":"my_slack_channel",
      "team_email":"my_team_email@xyz.com"
   }
}' | base64)
curl -v -i -X PUT -H "Accept: application/vnd.github.v3+json" -H "Authorization: token qqqqqqqqqqqqqq" -d "{\"message\": \"TEST-9876 add metadatafile\", \"content\": \"$content\"}" https://github.xyz.com/api/v3/repos/my_org/my_repo/contents/.metadata.json

Quite valuable indeed, grazie Andrea!

This helped me today, thank you.

Only to say that I'm very happy to have helped you @defrindr @jamlevi @elect86 and @zpostfacto
