## How to control OpenRefine 3.3+ with cURL (and jq) in Bash scripts
tested on Fedora 32 with bash 5.0.17 and curl 7.69.1
### Quick start
1. Clone this gist
```
git clone https://gist.github.com/d76bd27fbc4b8ab6d683822cdf61f81d.git bash-refine
```
2. Execute all supplied examples for a quick demo
```
cd bash-refine
./templates.sh
```
### Build your own workflow
3. Copy minimal pre-structured script to a new file
```
cp minimal.sh myworkflow.sh
```
4. Use the templates in `templates.sh` to develop your workflow
