# MaksIT Unified Scheduler Service
**MaksIT UScheduler** schedules PowerShell scripts and keeps console programs running on Windows and Linux. The same program is the window and the service.
- Register, start, stop, and unregister ask for approval in place. The window stays unelevated.
- Edit when a script runs, then **Launch** to start it now and follow its log. That run ignores the schedule and the minimum interval.
- A console program starts and stops with the service, and restarts when it exits.
- Scripts show a description and platform. A script for the other operating system stays in the list, grayed out, and does not run.
- Example scripts ship disabled. Enable the ones you want. An install does not overwrite a script file that is already there.
- Windows and Linux. [Apache 2.0](LICENSE.md).

## Requirements
- 64-bit Windows 10 or Windows 11, or Linux
- Administrator approval once, to register the service and prepare the scripts and logs folders
- From source: [.NET 10 SDK](https://dotnet.microsoft.com/download)
The window itself does not need administrator rights.
## Getting started
Install a build from [Releases](https://github.com/MAKS-IT-COM/uscheduler/releases): a portable zip, a Windows setup exe, or a Flatpak of the window. Or from `src/`:
```powershell
dotnet run --project src/MaksIT.UScheduler.UI
```
The Windows setup exe offers **Standard** or **Portable**. **Options** sets the scripts and logs folders. They start at `C:\MaksIT\Scripts` and `C:\MaksIT\Logs`. A portable install keeps Scripts and Logs inside the install folder unless those paths are changed. The portable zip is the same layout: launch `MaksIT.UScheduler.UI.exe` or `Start-UScheduler.bat`.
**Standard** (default):
| Location | Purpose | Who can write |
|----------|---------|----------------|
| `C:\Program Files\MaksIT\UScheduler` | `MaksIT.UScheduler.UI.exe` (window, and the service when started with `--service`) | Administrators |
| `C:\MaksIT\Scripts` | Scheduled scripts. Bundled examples are copied only when that folder or file is missing | Users (after install) |
| `C:\MaksIT\Logs` | Service and script logs | Users (after install) |
| `%ProgramData%\MaksIT\UScheduler\settings.json` | Shared schedule configuration | Users (after install) |
| `%AppData%\MaksIT\UScheduler\settings.json` | Per-user UI prefs (window size, position, and What's New) | Current user |
**Portable** (everything in one folder):
| Location | Purpose |
|----------|---------|
| *Install folder* | `MaksIT.UScheduler.UI.exe` |
| *Install folder*`\Scripts` | Scheduled scripts |
| *Install folder*`\Logs` | Service and script logs |
| *Install folder*`\Data\settings.json` | Shared schedule configuration |
| *Install folder*`\Data\ui-settings.json` | UI prefs |
A `portable` file in that folder, or a parent folder, marks the layout. The Users group can modify `Scripts`, `Logs`, and `Data`, so the window can stay unelevated.
Register, start, stop, and unregister from the window, or from an elevated shell. On Windows the file is `MaksIT.UScheduler.UI.exe`. With no arguments it opens the window. `--service` is what Windows SCM and systemd start; it does not open a window.
```powershell
MaksIT.UScheduler.UI --install
MaksIT.UScheduler.UI --start
MaksIT.UScheduler.UI --status
MaksIT.UScheduler.UI --stop
MaksIT.UScheduler.UI --uninstall
MaksIT.UScheduler.UI --prepare-data
MaksIT.UScheduler.UI --prepare-data --portable
```
| Command | Short | Description |
|---------|-------|-------------|
| `--service` | | Run the scheduler without a window |
| `--install` | `-i` | Install the service (Windows SCM or systemd) |
| `--uninstall` | `-u` | Stop and remove the service |
| `--start` | | Start the service |
| `--stop` | | Stop the service |
| `--status` | | Query service status |
| `--prepare-data` | | Create scripts, logs, and shared settings |
| `--portable` | | With `--install` or `--prepare-data`: keep data in the install folder |
| `--help` | `-h` | Show help |
`--install` on Linux writes `/etc/systemd/system/MaksIT.UScheduler.service` (`Type=notify`) and enables the unit.
Bundled examples, copied only when missing:
- [Hyper-V Backup](src/Scripts/HyperV-Backup/README.md)
- [Native-Sync](src/Scripts/Native-Sync/README.md)
- [File-Sync](src/Scripts/File-Sync/README.md) — [FreeFileSync](https://freefilesync.org/) batch job
- [Windows-Update](src/Scripts/Windows-Update/README.md)
- [Scheduler template module](src/Scripts/SchedulerTemplate.psm1)
They are listed in the default configuration and **disabled**. Enable one in the window, or set `"Disabled": false` in the shared settings file.
## Linux (Flatpak)
GitHub releases include `maksit-uscheduler-{version}.flatpak`.
**User** (this account only):
```bash
flatpak install --user ./maksit-uscheduler-{version}.flatpak
flatpak run com.maks_it.uscheduler
```
**System** (all users):
```bash
sudo flatpak install --system ./maksit-uscheduler-{version}.flatpak
flatpak run com.maks_it.uscheduler
```
Uninstall: `flatpak uninstall --user com.maks_it.uscheduler` or `sudo flatpak uninstall --system com.maks_it.uscheduler`.
The previous id `com.maks_it.UScheduler` is replaced by this lowercase id. Uninstall the old app before installing the new bundle if it was installed.
If GNOME or KDE does not show a launcher icon, `flatpak run` may warn that `/var/lib/flatpak/exports/share` and `~/.local/share/flatpak/exports/share` are not on `XDG_DATA_DIRS`. Log out and back in once so the session picks up those paths.
Linux uses X11/XWayland (Avalonia native Wayland still hangs on GNOME). The sandbox grants `--filesystem=home` for scripts and logs. The Flatpak is the window. Register the same program with systemd on the host when it should run at boot. AppStream and the desktop file live in [`data/`](data/).
## Configuration
Host logging stays in shipped `appsettings.json` next to `MaksIT.UScheduler.UI.exe`. The schedule is the shared settings file: `%ProgramData%\MaksIT\UScheduler\settings.json` on a standard install, or `{install folder}\Data\settings.json` when portable.
```json
{
"Configuration": {
"ServiceName": "MaksIT.UScheduler",
"LogDir": "C:\\MaksIT\\Logs",
"ScriptsDir": "C:\\MaksIT\\Scripts",
"Powershell": [
{ "Path": "File-Sync\\file-sync.ps1", "IsSigned": true, "Disabled": false },
{ "Path": "C:\\MaksIT\\Scripts\\AnotherScript.ps1", "IsSigned": false, "Disabled": true, "Platforms": ["Windows"], "Description": "Windows-only example" }
],
"Processes": [
{ "Name": "My app", "Path": "C:\\Tools\\MyApp.exe", "Args": ["--option"], "Directory": "C:\\Tools", "RestartOnFailure": true }
]
}
}
```
`ServiceName`, `LogDir`, and `ScriptsDir` are optional. Defaults are `MaksIT.UScheduler`, `C:\MaksIT\Logs`, and `C:\MaksIT\Scripts`.
A relative script path is resolved against `ScriptsDir`. A relative process path is resolved against the install directory.
| Property | Default | Role |
|----------|---------|------|
| `Path` | required | Script or executable |
| `Name` | empty | Label in the list. Empty uses the file name |
| `Description` | empty | Short text under the script name |
| `Platforms` | empty (both) | `Windows` and/or `Linux`. The service skips a script that does not match this host |
| `IsSigned` | `true` | `true` is AllSigned. `false` is unrestricted |
| `Disabled` | `false` | Skip this script or program |
| `Args` | empty | Process arguments |
| `Directory` | empty | Process working directory. Empty uses the executable's directory |
| `RestartOnFailure` | `true` | Start the program again after any exit. `false` leaves it stopped |
| `RestartDelayMs` | `0` | Wait before a restart after a run that lasted at least `ThrottleMs` |
| `ThrottleMs` | `1500` | A shorter run waits at least this long before the next start, and longer if it keeps exiting immediately |
Scripts run together in a runspace pool. Each console program runs beside the others. A failure in one does not stop the service or the others. The same script or program is not started twice while it is still running. Stopping the service stops the programs too. A program that exits sooner than `ThrottleMs` waits before the next start, so a crash loop does not spin. Its standard output and error go to that program's log.
File logging uses `LogDir`. On Windows, service events also go to the Application event log under the `MaksIT.UScheduler` source.
## Scheduler module
[`SchedulerTemplate.psm1`](src/Scripts/SchedulerTemplate.psm1) is the schedule, lock file, and `Write-Log` used by the bundled scripts. Version 1.0.3.
`Write-Log` writes `[Level] message` to the output stream unless the host is an interactive console, so a launch from the window is recorded in the script log. An interactive console still prints a colored line with a timestamp.
```powershell
param (
[switch]$Automated,
[string]$CurrentDateTimeUtc
)
Import-Module "$PSScriptRoot\..\SchedulerTemplate.psm1" -Force
$Config = @{
RunMonth = @()
RunWeekday = @()
RunTime = @("22:52")
MinIntervalMinutes = 10
}
function Start-BusinessLogic {
Write-Log "Executing business logic..." -Automated:$Automated
}
Invoke-ScheduledExecution -Config $Config -Automated:$Automated -CurrentDateTimeUtc $CurrentDateTimeUtc -ScriptBlock {
Start-BusinessLogic
}
```
| Function | Role |
|----------|------|
| `Write-Log` | Info, Success, Warning, or Error |
| `Invoke-ScheduledExecution` | Schedule, lock file, and the callback |
| `Get-CredentialFromEnvVar` | Credential from a Base64 machine environment variable |
| `Test-UNCPath` | Whether a path is a UNC path |
| `Send-EmailNotification` | SMTP mail, with optional SSL and a credential |
Copy the template, set `$Config`, and implement `Start-BusinessLogic`. Add the script in the window, or in the shared settings file.
## Tests
```powershell
utils\Invoke-TestEngine.bat
```
Or `dotnet test src/MaksIT.UScheduler.Tests`. The test engine rewrites the shields.io coverage badges at the top of this file. Commit those URL changes with the test or release work.
