From the Linux man pages: setuid sets the effective user id of the current process.
在Linux手册页上指出：setuid设置当前进程的有效用户id。
Sem_perm.cuid and sem_perm.uid are set to the effective user id of the calling process.
sem_perm . cuid和sem_perm . uid被设置为调用进程的有效用户id。
The effective user ID of the calling process must be that of the super-user or match the creator or owner of the semaphore set.
调用进程的有效用户ID必须是超级用户，或者可以与该信号量集的创建者或所有者匹配的用户。
To do this, either the effective user ID of the porcess must equal the owner ID of the file, or the process must have write permission for the file.
这时，进程的有效用户ID必须和文件的拥有者ID一致，或者进程必须拥有文件的写权限。
This allows a set-user-ID (other than root) program to drop all of its user privileges, do some un-privileged work, and then re-engage the original effective user ID in a secure manner.
这使set-user-ID（非根）程序能够放弃它的所有用户特权，执行一些非特权操作，然后恢复原来的有效用户ID。
For this case, the effective user ID of the process must equal the owner ID of the file, or the process must be a superuser process. Merely having write permission for the file is not adequate.
这种情况下，进程的有效用户ID等于文件拥有者的ID，或者进程是超级进程，仅仅有文件的写权限是不够的。
The traditional user ID and password method of authentication is no longer effective or sufficient in this day and age where security is a major concern for large infrastructures.
如今，对于大型的基础设施来说，安全是需要重点考虑的一个问题，传统的使用用户ID和密码进行验证的方法不再有效，或者说这种方法不再能包办一切。
In order to find the effective database authorization ID, you need to ensure that the external user is who they say they are, and then map their external user ID to an internal DB2 authorization ID.
为了找到有效数据库授权ID，需要确保外部用户就是所声称的用户，然后将其外部用户ID映射到内部DB 2授权ID。
Before knowing if a user is authorized to do a particular operation, DB2 must be able to know the effective database authorization ID of the external user, and in which groups that user belongs.
在获知用户是否被授权进行特定操作之前，DB 2必须能够获知外部用户的有效数据库授权ID及其所属的组。
The effective database authorization ID (authid) of the external user performing a particular task
执行特定任务的外部用户的有效数据库授权ID（authid）
If your prompt does not include your user id, then you can use the whoami command to check your current effective id.
如果您的提示没有包括用户id，可以使用whoami命令来检查您当前有效的id。
If the effective UID of the caller is root, the real UID and saved set-user-ID are also set.
如果调用者的有效UID是根用户，那么还设置真实uid和保存的set - user - ID。
If the effective UID of the caller is root, the real UID and saved set-user-ID are also set.
如果调用者的有效UID是根用户，那么还设置真实uid和保存的set - user - ID。
