Linux OSBot Launcher

[Bobbey]

I was getting annoyed by osbot installing updates to the home directory and me having to give it executable permissions over and over and looking for the correct file to launch. Therefore I've written a script that creates an application entry so you can just search with the SUPER key on your keyboard and then typing "osbot". The installed script will find the latest jar in your home folder and launch that.

Tested on Ubuntu. May work on Fedora, Debian and their derivatives.

 

 

Note: before installing, make sure there is any osbot jar present in the home directory /home/username/osbot x.x.x.jar

Installer
Note: the installer requires "osbot_icon.png" in the working directory. This icon needs to be 48x48 or 64x64 or 128x128 etc. You can use this image for example. Don't forget to rename it after downloading.

$ sh install.sh

1. Creates a script at /usr/local/bin/osbot which finds and launches the latest osbot.jar in the home directory.
2. Makes the script executable
3. Copies osbot_icon.png to /usr/share/icons/osbot_icons/osbot_icon.png and gives it the correct permissions
4. Creates the desktop entry ~/.local/share/applications/osbot.desktop and gives it the correct permissions
5. Reloads the application database

Logs can be found at /tmp/osbot_launcher.log
