Update-Script für easyname Support Bash-Snippets
|

|

Optionen:
|
||||
--dry-run, -n Zeigt nur was gemacht würde, ohne Änderungen
|
||||
--help, -h Zeigt diese Hilfe an
|
||||
|
||||
Das Script:
|
||||
1. Erstellt ein Backup des aktuellen Zustands
|
||||
2. Aktualisiert das Repository (git pull)
|
||||
3. Erneuert Symlinks der installierten Tools
|
||||
4. Macht neue Scripts ausführbar
|
||||
|
||||
Beispiele:
|
||||
$0 Führt Update durch
|
||||
$0 --dry-run Testet Update ohne Änderungen
