Re: shell object on Raspberry PI 4, GPIO control via pinctrl

i think it is often easiest, to do the job control in your script, rather than within the patch.

that is: instead of sending trying to send things like `[command 1 && command 2 && command 3(`, create a wrapper script:
```
#!/bin/sh
for x in "$@"; do
  command "$x" || exit $?
done
```

and then call it as `[wrapperscript 1 2 3(`
