我在AIX上运行了以下命令，以便找出AIX 6.1上由进程200866打开的文件。
procfiles -nc 200866 并得到以下示例输出：
Current rlimit: 2000 file descriptors --------------------------------------------------------------------------------------------------------------- FD TYPE MODE DEV/RDEV UID GID OPMOD NAME --------------------------------------------------------------------------------------------------------------- 10 - rw-r--r-- 10, 4 root system R|NH|DY
任何人都可以帮我理解OPMOD列中NH和DY的含义吗？ 我GOOGLE了很多，但没有find任何相关的网页。 谢谢！
它们只是文件打开模式标志的缩写，您可以在没有-c标志的情况下看到更完整的标志。
我找不到缩写的文档，但标记名在open()文档中详细说明。 在您的具体示例中，这将是一个文件打开只读（ R ），与O_NSHARE （ NH ）和O_DELAY （ DY ）。
这里有一些与“生产”他们的C片段。
open("./1", O_RDONLY|O_DELAY); open("./2", O_RDONLY|O_NDELAY); open("./3", O_WRONLY); open("./4", O_RDWR|O_APPEND); open("./5", O_RDONLY|O_NSHARE); open("./6", O_RDONLY|O_RSHARE); open("./7", O_RDWR|O_CIO);
