unix - How do i diff two files from the web -


i want see differences of 2 files not in local filesystem on web. so, think if have use diff, curl , kind of piping.

something 

curl http://to.my/file/one.js http://to.my/file.two.js | diff

but doesn't work.

the unix tool diff can compare 2 files. if use <() expression, can compare output of command within indirections:

diff <(curl file1) <(curl file2)

so in case, can say:

diff <(curl http://to.my/file/one.js) <(curl http://to.my/file.two.js)

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).
