running command on nas system synology dsm error

[sentball]

the main error is grep -w not support, use command grep --help to know

seem the code line is echo "$options" | grep -qw devices || continue

[sentball]

i am running docker on synology dsm

I don't think pipework can function without GNU tools, sorry!

(i.e. the grep on the synology seems to be a lightweight version, missing options needed by pipework.)

Sorry again!
