Install
ScriptKitty installs on Linux today. In testing The source is not published yet, so there is no download on this page.

Today it has run only in throwaway test machines. Until it leaves testing, put it on a machine you can lose.
Requirements
These are the requirements for the Linux build.
- A kernel with fanotify permission events. It has run on 6.12 only.
- Root, for the service.
- Python 3, with only its standard library.
- Disks formatted ext4, xfs or btrfs.
Install and check
Run the installer from the source folder. It installs and starts the service.
sudo ./install.sh # from the source folder; installs and starts the service
sk # how things are, and the latest changes
sk status # what is watched, what is left out, room held
See the first minute for what these show.
Uninstall
The same script removes it.
sudo ./install.sh --uninstall

Cloud commands
Coming for real clouds. The cloud engine is built and was tried only against made-up APIs, and never against a real cloud. The commands exist as follows.
| Command | What it does |
|---|---|
sudo sk cloud setup | Makes the engine's certificate and starts it. |
sudo sk cloud add-key GITHUB_TOKEN --host api.github.com | Gives the engine a real key for one host, read from input. It prints the stand-in the agent gets. |
sudo sk cloud env | Prints the lines to give the agent: the proxy, the certificate and the stand-ins. |
sk cloud status | Shows the state of the cloud engine. |
sk cloud list | Lists the cloud calls it wrote down. |
sudo sk cloud undo ID | Puts one call back. |
