问题 Im writing a school assignment in C to search through a file system for directories, regular files and symlinks. For now i use lstat to get information about items. So whats the difference between lstat fstat and stat system calls? 回答1: I was also searching for stat vs lstat vs fstat and although there is already an answer to this question, I'd like to see it formatted like that: lstat() is identical to stat() , except that if pathname is a symbolic link, then it returns information about the

python中os模块在windows下的使用

由 本秂侑毒 提交于 2020-02-26 02:21:22
今天学习了一下Python的os模块，主要是针对文件夹和文件路径的一系列操作。 与Python内置函数相比这里这里的函数功能更多样化，功能也更强大。但是学习过程中我发现很多函数都是只适用于unix系统，可能因为它是开源系统，涉及权限的api都是开放的缘故吧。但也正是如此，当我们再Windows上学习Python时，本来这个板块就难以理解，还具有不可操作性。学起来感觉很受打击。 所以这里把Windows上能用，且适用的函数记录下来，以便于以后复习： 1，os.lseek(fd，pos，how) 方法用于设置文件描述符 fd 当前位置为 pos, how 方式修改。（与内置函数类似但是多了一个文件描述符，pos：0代表开头，1代表当前，2代表结尾，how用一个int型表示方式。例10表示从pos往后数10个字节的位置。） 2.os.listdir() 方法用于返回指定的文件夹包含的文件或文件夹的名字的列表。这个列表以字母顺序。 它不包括 '.' 和'..' 即使它在文件夹中。（使用方法os.listdir(path)在Linux中dir或者ls命令也是相同的效果） 3.os.lstat() 方法用于类似 stat() 返回文件的信息,但是没有符号链接。在某些平台上，这是fstat的别名，例如 Windows。 4，os.fstat() 方法用于返回文件描述符fd的状态，类似 stat(

How to discern, if a directory is NFS-mounted from Ansible?

由 你说的曾经没有我的故事 提交于 2020-01-14 14:57:07
问题 I need to set up an application directory for a "hairy" app. Depending on the case, the directory may be local to each server participating, or shared among several servers via NFS. So, I need to be able to detect, whether the given path is local or NFS-accessed and skip some of the tasks in the latter case. What's the best way to detect this in an Ansible role? I tried using the stat module, but device_type seems to be set to 0 in all cases, NFS or local (XFS). On Linux I could invoke stat

Printing info of a file/director (inode)

Get file's owner and group using boost

问题 I want to get the owner and group from a file using boost::filesystem, but never found any way to do so. I can get the file's permissions, but as I don't know the file's owner this just doesn't mean anything. I found the posix fstat function, but again I'd like to use boost or another C++ library rather than C functions. 回答1: What you're asking to do is a Unix system call. But you don't want to call it? Why? What possible value could boost provide? It's not portability, as nothing outside of
