Just a note: hashbangs can't really be considered reliable either -- consider tarball-in-sh/other-script files (waf is a good example). Then there's stuff like gambas-compiled executables which also ship with valid hashbangs, and #!/usr/bin/haserl stuff which can contain lua bytecode after the hashbang line. The only requirement for valid hashbangs, afaict, is that the first two bytes are #!, and everything up to the \x20 or \n is resolvable to a valid filename. > [...] -- Kind regards, Loong Jin
