Jilles Tjoelker 604e8224f8 sh: Do not try to execute binary files as scripts. ... If execve() returns an [ENOEXEC] error, check if the file is binary before trying to execute it using sh. A file is considered binary if at least one of the first 256 bytes is '\0'. In particular, trying to execute ELF binaries for the wrong architecture now fails with an "Exec format error" message instead of syntax errors and potentially strange results.		2011-02-05 12:54:59 +00:00
