pcregrep installieren / Alternative

[etofi]

Hallo zusammen,

ich möchte regelmäßig folgende Script laufen lassen in dem pcregrep verwendet wird.
Leider ist pcregrep nicht verfügbar.

Gibt es einen Weg das nachzuinstallieren? Oder eine Alternative für pcregrep.
Ich bin leider nicht so der Profi was Regular Expressions angeht.

Wäre super wenn jemand eine Idee für mich hätte.
