No, I did some testing, and argv[0] seems to always be the command name that is used to execute the command; if it is found by virtue of being in the user's search path, only the command name itself is there. In shell scripts, however, $0 seems to be the full path to the script, or the path relative to the current directory when the script is started. It is easy enough for the script to tell which, by virtue of a leading /. So a shell script wrapper can be used to tell your program where it lives, through environment variables, executing the real program using the full path (and thus passing argv[0] the way the original poster likes), or an extra argument. --- Andy Tefft - new, expanded .sig - teffta@erie.ge.com ------------------------------ From: kmh@linux.stevens-tech.edu (Kurt M.

I just purchased a 486DX2-66 green motherboard. This is the kind of motherboard with the option to half the power to devices which are inactive after a certain period of time, and then reset the power consumption upon any sign of device activity. I know that this works very well for DOS, which doesn't really care what is happening to the system it is on. I wonder though, will Linux react favourably to devices having their power cut in half, without raising a fuss? Since my systems are running 24 hours a day, I'd be interested in upgrading all of my systems to green motherboards, so long as Linux will handle them well. At the same time, I don't want to cause problems by trying it. I've had unusual experiences with self-caching hard-drives hooked to Linux, and don't want to go through this again. Anybody else have a green motherboard, with these options enabled?

Linus has rejected the patches every time. *** Explanation for anyone who missed this thread last time *** When the kernel detects a shell script (magic number "#!") it will do the usual checks for accessibility, then open the file to read the command processor. Then it exec's the *command processor* with the filename on the command line. The command processor than opens the file in user space: race condition. The alternative proposed was passing the file argument as a file descriptor through the /proc filesystem; however, all of a sudden you have an essential kernel service *dependent* on having the /proc filesystem properly mounted; in fact, the patches I saw all hard-coded the name /proc and used it for all shell scripts. I am not too sure how well the system startup would have dealt with that. However, once again I am saying that this is the Wrong Thing to do. The kernel should assign the new process with the privileges by the user and the *binary* executed, which is the command processor. If the command processor can handle setuid scripts, and the sysadmin wants to enable them, it should be run as setuid root and convey the privileges itself. /hpa -- INTERNET: hpa@nwu.edu --- Allah'u'abha --- IBM MAIL: I0050052 at IBMMAIL HAM RADIO: N9ITP or SM4TKN FIDONET: 1:115/511 or 1:115/512 STORMNET: 181:294/1 or 181:294/101 Denied! ------------------------------ ** FOR YOUR REFERENCE ** The service address, to which questions about the list itself and requests to be added to or deleted from it should be directed, is: Internet: Linux-Misc-Request@NEWS-DIGESTS.MIT.EDU You can send mail to the entire list (and comp.os.linux.misc) via: Internet: Linux-Misc@NEWS-DIGESTS.MIT.EDU Linux may be obtained via one of these FTP sites: nic.funet.fi pub/OS/Linux tsx-11.mit.edu pub/linux sunsite.unc.edu pub/Linux End of Linux-Misc Digest ******************************
