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 Snap is available for [Red Hat Enterprise Linux (RHEL) 8](https://www.redhat.com/en/enterprise-linux-8) and RHEL 7, from the 7.6 release onward. The packages for RHEL 7, RHEL 8, and RHEL 9 are in each distribution’s respective [Extra Packages for Enterprise Linux](https://fedoraproject.org/wiki/EPEL) (EPEL) repository. The instructions for adding this repository diverge slightly between RHEL 7, RHEL 8 and RHEL 9, which is why they’re listed separately below. The EPEL repository can be added to **RHEL 9** with the following command: ``` sudo dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-9.noarch.rpm sudo dnf upgrade ``` The EPEL repository can be added to **RHEL 8** with the following command: ``` sudo dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm sudo dnf upgrade ``` The EPEL repository can be added to **RHEL 7** with the following command: ``` sudo rpm -ivh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm ``` Adding the *optional* and *extras* repositories is also recommended: ``` sudo subscription-manager repos --enable "rhel-*-optional-rpms" --enable "rhel-*-extras-rpms" sudo yum update ``` Snap can now be installed as follows: ``` sudo yum install snapd ``` Once installed, the *systemd* unit that manages the main snap communication socket needs to be enabled: ``` sudo systemctl enable --now snapd.socket ``` To enable *classic* snap support, enter the following to create a symbolic link between `/var/lib/snapd/snap` and `/snap`: ``` sudo ln -s /var/lib/snapd/snap /snap ``` 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?
