The 4 sets the setuid bit it tells the system to run the program as the file owner (:root) instead of as the user who invoked it (mike).
By the way you must be root to set that permission. Warning 0 this bit is one of the major sources for security problems in linux .. allowing a program run as a normal user to run as root. Use it with extreme caution. ----- Original Message ----- From: <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Monday, April 22, 2002 1:00 PM Subject: RE: problem with permissions > What is the 4 for???? > > -----Original Message----- > From: Hal Kellerman [mailto:[EMAIL PROTECTED]] > Sent: Monday, April 22, 2002 4:00 PM > To: [EMAIL PROTECTED] > Subject: Re: problem with permissions > > > try setting the permissions to 4777 not just 777 > > Hal > > ----- Original Message ----- > From: <[EMAIL PROTECTED]> > To: <[EMAIL PROTECTED]> > Cc: <[EMAIL PROTECTED]> > Sent: Monday, April 22, 2002 12:46 PM > Subject: problem with permissions > > > > How can I assign permission to a user "mike" to be able to shutdown the > > computer. > > > > I have tried to create a group and assign the group to the shutdown > command > > using chown, tried changing the permissions to 777 or rwxrwxrwx using > chmod > > shutdown, this doesn't work tells me I still need to be root.
