Python-Skript zum Entfernen von Strings aus Dateinamen und Verzeichnisnamen rekursiv

Dieses Python-Skript benennt Dateien und Verzeichnisse in einem angegebenen Ordner rekursiv um, indem ein angegebener String aus Dateinamen und Verzeichnisnamen entfernt wird. Es erfordert keine installierten Bibliotheken.

Beachte, dass dieses Skript getestet wurde, jedoch können wir nicht garantieren, dass es unter bestimmten Bedingungen keine Daten zerstört. Sichere deine Daten und verwende es mit Vorsicht(am besten mit --dry --verbose testen!)

Dies sind die Kommandozeilen-Optionen, die es bietet:

RemoveFromNames_usage.txt

usage: RemoveFromNames.py [-h] [-c] [--dry] [-D] [-F] [-i] [-v] dir remove_string

Process and rename files and directories by removing a specific string.

positional arguments:
  dir                   Input directory to scan recursively
  remove_string         String to remove from filenames and folder names

options:
  -h, --help            show this help message and exit
  -c, --compress_spaces
                        Compress multiple spaces into one
  --dry                 Dry run. Do not actually rename anything.
  -D, --no_dirs         Don't rename directories.
  -F, --no_files        Don't rename files.
  -i, --case_insensitive
                        Perform case-insensitive compare and replace.
  -v, --verbose         Print what is being renamed.
