Das Repository enthält Dateien zum automatischen Versenden von Einladungsmails für das Plenum.
|

|
||||
Das Shellskript ermittelt den kommenden Donnerstag, prüft, ob es ein erster
|
||||
Donnerstag des Monats ist, und bricht sonst ab, ersetzt im Einladungstext (Datei
|
||||
`email_text`) Platzhalter mit dem Datum des kommenden Donnerstag und verschickt
|
||||
den Text als E-Mail.
|
||||
|
||||
Die Service- und Timer-Dateien lassen systemd das Skript einmal wöchentlich
|
||||
ausführen.
