Der Stromanschluss ist derselbe wie beim Quartz64, somit kann ich alle meine Netzteile weiter benutzen.

Kleine Liste von Befehlen, die ich immer mal wieder brauche. Bis ich die im Kopf behalte, muss ich sie mir aufschreiben

Wenn man mit grep die Datei syslog durchsucht, geht das einwandfrei. Doch mit der Datei syslog.1 meint grep ein binary File vor sich zu haben und weigert sich.
rock64@rockpro64v_2_1:~$ sudo grep "Restic" /var/log/syslog.1 Binary file /var/log/syslog.1 matchesMit der Option -a behandelt grep die Datei als Textdatei.
rock64@rockpro64v_2_1:~$ sudo grep -a "Restic" /var/log/syslog.1 Sep 18 04:33:05 rockpro64v_2_1 root: Restic-Backup Script erfolgreich! 18.09.2018_04:30 Sep 18 04:35:06 rockpro64v_2_1 root: Restic-Backup erfolgreich überprüft! 18.09.2018_04:30Was ich auch immer wieder brauche, wenn ich dmesg nach irgendwas durchsuchen muss.
dmesg | grep -i memory dmesg | grep -E "memory|dma|usb|tty"dpkg
Wenn man Kamils Mainline runtergeladen hat und die .deb Dateien installieren möchte.
sudo dpkg -i *.debfind
ACHTUNG! Nicht ungefährlich der Befehl!
# Alle Dateien löschen, die älter als 5 Tage sind. find /daten -name "*.rdb*" -mtime 5 -exec rm {} \;Hier noch ein aktuelles Beispiel
## Nur die Datenbanken der letzten 30 Tage behalten find /mnt/nas/Sicherungen_Cloud/mysql/ -name "joomla*.sql" -mtime +30 -exec rm {} \;du
