Effective User ID
The effective UID (euid) and effective GID (egid) affect file creation and access. During file creation, the kernel sets the owner attributes of the file to the effective UID and effective GID of the creating process. During file access, the kernel uses the effective UID and effective GID of the process to determine if it can access the file.

Famous quotes containing the words effective and/or user:
“[Madness] is the jail we could all end up in. And we know it. And watch our step. For a lifetime. We behave. A fantastic and entire system of social control, by the threat of example as effective over the general population as detention centers in dictatorships, the image of the madhouse floats through every mind for the course of its lifetime.”
—Kate Millett (b. 1934)
“A worker may be the hammers master, but the hammer still prevails. A tool knows exactly how it is meant to be handled, while the user of the tool can only have an approximate idea.”
—Milan Kundera (b. 1929)
