The Linux “du” (Disk Usage) is a standard Unix/Linux command, used to check the information of disk usage of files and directories on a machine. The du command has many parameter options that can be used to get the results in many formats. The du com…

Files and Directories Introduction     In the previous chapter we coveredthe basic functions that perform I/O. The discussion centered on I/O for regular files-opening a file, and reading or writing a file. We'll now look at additionalfeatures of the…

If you accidentally added some files which should have been ignored, how do you get them out of version control without losing them? Maybe you have your own IDE configuration file which is not part of the project, but which took you a long time to se…

本篇主要介绍文件和文件系统中常用的一些函数,文件系统的组织结构和硬链接.符号链接. 通过对这些知识的了解,可以对Linux文件系统有更为全面的了解.   1 umask函数 之前我们已经了解了每个文件与权限相关的9个位(bit),我们现在来了解一下当每个进程创建文件时默认会设置该文件的文件权限(the file mode creation mask). umask函数设置该进程默认创建文件的权限掩码(the file mode creation mask),并且返回之前的权限掩码值. #incl…
