People who want to seriously study UNIX environment advanced programming may want to knock the example in the book and run a look at the effect. But for the novice, there may be some difficulty, because the example used in the header file and some functions do not know where, the compilation may also be problematic. This article here is an example of how to run the examples in this

This chapter focuses on a bunch of IDs. Actual user (Group) ID, valid user (Group) ID, save set user (Group) ID, file system user (Group) ID. And the secondary group ID.
The actual user ID is determined.

, because these two processes connect to two terminals and the terminals belong to users, UNIX is now a multi-user system. Therefore, although UNIX was immature in 1969, it was indeed a multi-process multi-user time-sharing system. The history of modern operating systems began. The first mature UNIX is UNIX v6, the ver
