### AppImageTool Detailed Usage

Source: https://github.com/appimage/appimagetool/blob/main/README.md

Lists all available options for appimagetool, including generating AppImages, listing files, embedding update information, signing, and verbose output.

```bash
Usage:
  appimagetool [OPTION...] SOURCE [DESTINATION] - Generate AppImages from existing AppDirs

Help Options:
  -h, --help                  Show help options

Application Options:
  -l, --list                  List files in SOURCE AppImage
  -u, --updateinformation     Embed update information STRING; if zsyncmake is installed, generate zsync file
  -g, --guess                 Guess update information based on environment variables set by common CI systems (GitHub actions, GitLab CI)
  --version                   Show version number
  -v, --verbose               Produce verbose output
  -s, --sign                  Sign with gpg[2]
  --comp                      Squashfs compression
  -n, --no-appstream          Do not check AppStream metadata
  --exclude-file              Uses given file as exclude file for mksquashfs, in addition to .appimageignore.
  --runtime-file              Runtime file to use
  --sign-key                  Key ID to use for gpg[2] signatures
  --sign-args                 Extra arguments to use when signing with gpg[2]
```

--------------------------------

### Generate AppImage from AppDir

Source: https://github.com/appimage/appimagetool/blob/main/README.md

Basic usage to generate an AppImage from an existing AppDir. Ensure the ARCH environment variable is set if architecture cannot be determined automatically.

```bash
ARCH=x86_64 ./appimagetool-x86_64.AppImage some.AppDir
```
