Git diff HEAD before ever commiting -


i'm quite new git. question concern execution of git diff head command before ever commiting. know head doesnt exist until had commited something. how do difference between working directory & initial state of repo.

i know command gives difference between working directory & index (stage): 

git diff

and following command gives difference between index & repo:

git diff --cached

i guess git commit --allow-empty without adding if you really want diff first "real" commit adds things.

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
