## Usage

The shell plugin executes shell commandos after set, get or error.

The configuration keys

- `execute/set`
- `execute/get`
- `execute/error`

are used to store the shell commands.

The configuration keys

- `execute/set/return`
- `execute/get/return`
- `execute/error/return`

can be compared against the return values of the shell commandos.

## Example

```sh
# Create temporary file
kdb set system/tests/tempfile $(mktemp)

# Mount plugin and specify plugin configuration
sudo kdb mount shell.ini system/tests/shell ini array= shell execute/set="echo set >> $(kdb get system/tests/tempfile)"

cat $(kdb get system/tests/tempfile)
#>

# Execute `set` command
kdb set system/tests/shell
#> Create a new key system/tests/shell with null value

cat $(kdb get system/tests/tempfile)
#> set

# Undo modifications
rm $(kdb get system/tests/tempfile)
kdb rm -r system/tests/shell
sudo kdb umount system/tests/shell
```
