apache - Difference between apachectl and apache2 -


i have tried restart apache server, new this. curious know apache2 restart does? apachectl restart do?

assuming on ubuntu or likes, man apache2 indicates following:

in general, apache2 should not invoked directly, rather should invoked via /etc/init.d/apache2 or apache2ctl.

fyi: apachectl alias of apache2ctl nowadays

as best practice, advised issue sudo apache2ctl graceful

the graceful argument, intended meaning, offers more stable way restart apache process letting child processes finish ongoing tasks before reloading configurations.

cf man apache2ctl

restart:

restarts apache daemon sending sighup.

graceful:

gracefully restarts apache daemon sending sigusr1. if daemon not running, started. differs normal restart in open connections not aborted.

here reference signalling sigusr1 opposed sighup.

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).
