yes [string] — /usr/bincoreutilsstdin stdout - datei -- opt --help --version
Der Befehl yes gibt den angegebenen String
(oder in der Voreinstellung »y«) unendlich oft mit jeweils einem
String pro Zeile aus.
$ yes nochmal nochmal nochmal nochmal ...
Obwohl es auf den ersten Blick nutzlos erscheint, kann
yes perfekt geeignet sein, um aus interaktiven
Befehlen Batch-Befehle zu machen. Wenn Sie eine lästige Meldung wie
»Sind Sie sicher, dass Sie das tun wollen?« loswerden wollen, pipen
Sie die Ausgabe von yes in die Eingabe des
entsprechenden Befehls, so dass all diese Fragen beantwortet
werden:
$ yes | interaktiver_befehlWenn interaktiver_befehl
abgearbeitet ist, wird auch yes beendet.
