Error 'File is a symlink to a non-existent target'
lazarus
While working through two active buffers in Emacs, sum.cpp and template.cpp, I accidentally shut down my laptop (Ubuntu 15.04 (Vivid Vervet)) without closing Emacs, and without saving these two files.
When I restarted the laptop and listed directory content in Emacs by C - x C - f /C++/, I got the following.
What does the line mean after .#sum.cpp?
lrwxrwxrwx 1 anupam anupam 41 Aug 6 00:53 .#sum.cpp -> [email protected]:1438790786
I know Emacs saves the unsaved buffer by # by autosave, but when accessing #sum.cpp why is it showing the following?
file is a symlink to non-existent target?

The autosaved file is #sum.cpp#. The symlink .#sum.cpp is used by Emacs to store some internal data (seems like user name, host name and some timestamp)
As the target of a symlink is just some short text (that is resolved as a path if you access the symlink's content), symlinks are sometimes used to store small amounts of data. In that case the target most likely isn't a valid file path and you get an error if you try to access it.
That's because creating a symlink is an atomic operation: Either the symlink is created with full content or it's not created at all. In contrast creating a regular file and filling it with content is not atomic and in case of an error you may end up with an empty file or only partial content.
