I have made the following command to be able to match the string from the beginning of the line until the first occurrence of ".enabled" as long as there are no "." in between.

`grep -Po '^\K[\w-]*?(?=\.enabled)'`

input:

```
a-b-c.a.enabled.xxx.xx
a-b-c.a.b.enabled.xxx.xx
a-b-c.enabled.xxx.xx

```

output:

```
a-b-c

```

It runs properly on my local env with grep v3.1 but on Busybox v1.28.4 it says "**grep: unrecognized option: P**"

For that reason, I would like to convert this command to sed. Any input would be really helpful.
