An independent Linux alternative inspired by RegistryChangesView for comparing system and project configuration states before and after software updates or edits, it captures compressed .json.gz directory snapshots and renders clear line-by-line unified diffs. Key Features: * Compressed Directory State Snapshots: Captures read-only .json.gz state archives of host /etc directories, ~/.config folders, and project trees (.conf, .ini, .yaml, .toml, .env, .json, .service) including file checksums, permissions, timestamps, and text lines. * Added, Modified, and Deleted Summary: Compares any two saved snapshots or compares a saved baseline snapshot directly against a live directory on disk. * Unified Line-by-Line Diff Viewer: Renders color-highlighted unified diffs showing exact added and removed configuration lines alongside permission mode and byte size changes. * Change Breakdown and Patch Export: Displays change distribution charts by file extension and subdirectory, and exports standard .patch unified diffs, CSV tables, and JSON reports.

They update automatically and roll back gracefully. Snaps are discoverable and installable from the [Snap Store](https://snapcraft.io/store), an app store with an audience of millions. ### Enable snapd If you’re running [Ubuntu 16.04 LTS (Xenial Xerus)](https://www.ubuntu.com/) or later, including [Ubuntu 18.04 LTS (Bionic Beaver)](https://www.ubuntu.com/desktop/features) and [Ubuntu 20.04 LTS (Focal Fossa)](https://wiki.ubuntu.com/FocalFossa/ReleaseNotes), you don’t need to do anything. Snap is already installed and ready to go. For versions of Ubuntu between [14.04 LTS (Trusty Tahr)](https://wiki.ubuntu.com/TrustyTahr/ReleaseNotes) and [15.10 (Wily Werewolf)](https://wiki.ubuntu.com/WilyWerewolf/ReleaseNotes), as well as Ubuntu flavours that don’t include *snap* by default, *snap* can be installed from the Ubuntu Software Centre by searching for *snapd*. Alternatively, snapd can be installed from the command line: ``` sudo apt update sudo apt install snapd ``` Either log out and back in again, or restart your system, to ensure snap’s paths are updated correctly. ### Install Configuration Snapshot Comparator To install Configuration Snapshot Comparator, simply use the following command: ``` sudo snap install config-snapshot-differ ``` ### Other popular snaps… [See more...](https://snapcraft.io/search?categories=featured) [See more in Featured](https://snapcraft.io/search?categories=featured) ### More things to do… #### [Get the snap store](https://snapcraft.io/snap-store) Browse and find snaps from the convenience of your desktop using the snap store snap. #### [Learn more about snaps](https://snapcraft.io/docs) Interested to find out more about snaps?
