In startos (with the ypkg packages), their app store somehow can download and install packages, without the prompt of any root or user password, to the root protected folders of /usr ...etc. However their command line program (using same package format) requires my password (I am a sudoer though).
My questions: Is there any way to do this with the ubuntu software center? How does this work? (allow a program root access without password from user)
ok cool, could you explain what u+s, as far as I know, is it user add setuid? – agz – 2013-01-13T18:54:17.620
1The 'u' tells chmod to modify the permission bits of the user (owner) of the file (type ls -l 'filename' on the terminal). The '+' means to add to the permission bits. The 's' means to turn on the setuid bit, meaning that whoever runs the file will have the permissions of the owner of the file. – WikiWitz – 2013-01-13T19:19:35.130
