### Upgrade sshm
|
||||
|
||||
```bash
|
||||
sshm upgrade
|
||||
```
|
||||
|
||||
Automatically checks for the latest version on GitHub and upgrades sshm if a newer version is available. The script will:
|
||||
- Check for updates from the GitHub repository
|
||||
- Display the current and available versions
|
||||
- Show the installation path (`/usr/local/bin/sshm`)
|
||||
- Ask for confirmation before proceeding
|
||||
- Download and install the latest version
|
||||
- Verify the installation
|
||||
|
||||
The upgrade will attempt to install to `/usr/local/bin/sshm` (may require sudo), and fall back to `~/.local/bin/sshm` if needed.

||||

||||
