By default when you create a user or group in AIX, it simply assigns it the next available UID or GID number.
默认情况下在AIX中创建用户或组时，它只是分配下一个可用的UID或GID编号。
It's important to understand that whenever you change a UID or GID, you affect the permission levels of files in AIX.
需要理解的重要一点是，在更改uid或GID时将会影响到AIX中文件的权限级别。
Sometimes you need to change a UID or GID because you're migrating servers or applications from one server to another.
有时，在从一个服务器到另一个服务器迁移服务器或应用程序时将需要更改UID 或GID。
If the script finds a line in the UID or GID file for a user or group that does not exist on the system, the line is simply skipped.
如果脚本在UID或GID文件中找到的用户或组在系统中不存在，那就跳过该行。
Changing a UID or GID causes the ownership of all the files previously owned by that user or group to change to the actual integer of the file's previous owner.
更改uid或GID会导致以前由该用户或组拥有的所有文件的所有权更改为该文件的以前所有者的实际整数。
Changing a uid or gid causes the ownership of all the files previously owned by that user or group to change to the actual integer representing the file's previous owner.
更改一个uid或gid将导致此前由该用户拥有的所有文件的所有权更改为表示该文件的以前所有者的实际整数。
Before changing GID or UID Numbers, it is important to stop all running applications and have all users log off of the server.
在更改gid或uid编号之前，停止所有正在运行的应用程序并且让所有用户从服务器注销很重要。
This is because the system stores the UID and GID number for the owner and group on each file rather than storing a user or group name.
这是因为系统在每个文件中存储的是所有者和组的UID和GID编号，而不是用户或组名称。
If a new user or group is created with the old UID 203 or the old GID 7, then this new user or group will become the owner and group of every file on the system that the user previously owned.
如果新用户或组是使用旧uid 203或旧GID7创建的，则此新用户或组将成为系统上该用户以前拥有的每个文件的所有者和组。
On my system, my primary group is group id (GID) 501, or the group named strike. I also belong to three other groups.
在我的系统中，我的主要组的组id (GID)为501，该组名为strike。
On my system, my primary group is group id (GID) 501, or the group named strike. I also belong to three other groups.
