Code:
cat *.* | grep pattern

Wie kann ich mir zu jeder Zeile noch den Dateinamen ausgeben lassen, in dem "pattern" gefunden wurde?
bei grep -H bekomm ich ja leider nur "(standard input):" angezeigt...

Naja...
Code:
grep -l <pattern> *.*

Das gibt dir einfach die Dateien an, welche <pattern> enthalten. Willst du zusätzlich zum Dateinamne auch noch die betreffende Zeile sehen, in der pattern vorkommt, mache einfach:
Code:
grep <pattern> *.*

Wozu den cat?
Code:
grep -H Suchmuster *

Sucht das Suchmuster in allen Dateien und zeigt den Dateinamen und die Zeile an.
