Das folgende Konstrukt funktioniert mit den GNU Versionen von xargs, mv und find, so wie es die meisten Linuxdistributionen mitbringen.
Manchmal hat man über mehrere Verzeichnisse verteilt gleichartige Dateien, die man in einen gemeinsamen Ordner bringen möchte. Händisch geht das natürlich, das kann aber auch unübersichtlich werden. Eine geschickte Verkettung von vorhandenen Kommandos erleichtert dem Anwender dabei das Leben.
find . -name "*.mobi" -print0 | xargs -r0 mv -t ~/tmp/
Das find-Kommando sucht die Dateien mit dem genannten Muster ab dem aktuellen Verzeichnis.
Das xargs-Kommando führt dann für jede gefundene Datei den mv-Befehl aus. Hier wird über die -t Option ein GNU-spezifisches Feature aktiviert, bei dem immer zuserst das Zielverzeichnis angegeben wird. Die zusätzlichen Optionen bei find und xargs sorgen für korrektes Quoting der Dateinamen, wenn Leer- und Sonderzeichen enthalten sind.
Ein praktisches Beispiel sähe wie folgt aus:
Find ergibt folgendes Resultat:
./a/a.mobi
./b/b.mobi
xargs führt folgende Kommandozeilen aus:
mv -t ~/tmp/ ./a/a.mobi
mv -t ~/tmp/ ./b/b.mobi

Buffalo LinkStation Mini (illustration only)
Some years ago I purchased a Buffalo LinkStation Mini, a small NAS device for backup purposes. This device works quite well but until today, I didn’t have access to the builtin Wake-on-LAN feature from Linux.
Under Windows, the NAS boots as soon as the PC side software issues a special start request. After a little internet search, I found the necessary information and a small bash script to achieve this under Linux. I have adapted the wakeup script a bit and added a feature to disable the wakeup request via a second script. A third script queries the status of the NAS, both on the network and the state of the local wakeup script.
The wakeup script is intended to be run from the user’s Autostart sequence. The helpers can be called when needed.
Some icons are included.
The script needs bash,. zenity, notify-send and wakeonlan. The latter is a Ubuntu package and should be available in your distro as well.
The MIT License applies to this software. It works for my Buffalo LinkStation Mini, maybe for others too but I cannot guarantee this. You are on your own but, hey, the software is free for modification
