Skype on Linux allows to launch multiple instances (one for work account, one for private or other). To launch it you just need to append –dbpath=/path/to/skype/database/folder. Below is a simple launcher that will scan current directory for folders named .Skype_<instanceName> and present you with a list of instances with checkboxes to launch them.
Launcher has a very simple look but it works just as it should. And it is basically two lines of code. Below is a bash code that will produce this window.
