Today I just used a command as below:
$ mv win_* *
and got an unexpected result.
Of course I had some folders named with 'win_*' under current directory, such as 'win_core'. After the command is done, I can not find these folders anywhere in the file system.
It is a bit confusing, the destination does not seem valid
apparently but the command is executed without any warnings, and unluckily, my files are gone.
