Accidently deleted wchar.h in ubuntu
I was working with some files in usr/lib and usr/include where I accidently deleted wchar.h header file of ubuntu. Is there any way by which I can retrieve the file back or get the file online?
Solution 1:
dpkg -S wchar.h will tell you which installed package contains a file with said name. Once you identified the matching occurrence/path—which you can provide as well as part of the previous query if you already know it in advance—, just reinstall said package (e.g., using apt install --reinstall libc6-dev).
