| 1 | +# Usage: scoop download <app> [options] |
| 2 | +# Summary: Download apps in the cache folder and verify hashes |
| 3 | +# Help: e.g. The usual way to download an app, without installing it (uses your local 'buckets'): |
| 4 | +# scoop download git |
| 5 | +# |
| 6 | +# To download an app from a manifest at a URL: |
| 7 | +# scoop download https://raw.githubusercontent.com/ScoopInstaller/Main/master/bucket/runat.json |
| 8 | +# |
| 9 | +# To download an app from a manifest on your computer |
| 10 | +# scoop download path\to\app.json |
| 11 | +# |
| 12 | +# Options: |
| 13 | +# -f, --force Force download (overwrite cache) |
| 14 | +# -h, --no-hash-check Skip hash verification (use with caution!) |
| 15 | +# -u, --no-update-scoop Don't update Scoop before downloading if it's outdated |
| 16 | +# -a, --arch <32bit|64bit> Use the specified architecture, if the app supports it |
