Seth Arnold <mailto:seth.arnold () canonical com> Thursday, September 25, 2014 3:10 PM Which systems go through /bin/sh for the exec*() family of functions?
i don't have an exhaustive list. my friends at $dayjob told me to use debian, so i am. i see this: http://manpages.debian.org/cgi-bin/man.cgi?query=execv&apropos=0&sektion=0&manpath=Debian+7.0+wheezy&format=html&locale=en which contains this text:
If the header of a file isn't recognized (the attempted execve(2) <http://manpages.debian.org/cgi-bin/man.cgi?query=execve&sektion=2&apropos=0&manpath=Debian+7.0+wheezy&locale=> failed with the error ENOEXEC), these functions will execute the shell (/bin/sh) with the path of the file as its first argument. (If this attempt fails, no further searching is done.)
i now see that this only applies to execlp() and execvp(), not to the entire family.
