Is there any way to clear my Skype chat history in Fedora.My skype version is 188.8.131.52 and the fedora version is Version 3.14.2.
For single chats, go to history, you right click on a conversation and delete it via the popup menu. For global, go to Tools > Options > Privacy and click on Delete All Chat History
As an aside, skype keeps its data in an sqlite database which you can access directly. Details for similar poking about the database can be found here: http://www.huesler-informatik.ch/2014/08/29/exporting-skype-conversations-on-osx/ which I found useful when I was trying to import contacts from one account to another.
