I'm not Paul, but that's simple. Setuid bit is ignored for scripts. The reason for it is - the only thing that's able to spawn a process is an executable, which has certain format (ELF for Linux, possibly a.out - that depends on a kernel configuration). Every time you execute a script, you, in fact, are invoking script interpreter (probably /bin/sh in this case), which, in turn, executes your script. So, to make your script work you can: a) Bad idea. Set suid bit on an appropriate script interpreter. b) So-so idea. Write your own BINARY executable and set suid bit on it. c) Good idea. Use sudo(1). Reco -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe". Trouble? Contact [email protected] Archive: http://lists.debian.org/[email protected]
