What is an inodeIn the unix/linux system, on the surface, the user opens the file by file name, in fact, the system inside this process is divided into three steps: First, the system to find the file name corresponding to the inode number, and secondly, through the inode number, to obtain inode information; Based on the Inode information, locate the block where the file data resides and read the data.The area of the stored file meta-information (the creator of the file, the date the file was cre
The functions of these three functions are consistent and are used to obtain file-related information, but apply to different file objects. For the pathname parameter given in the function, the STAT function returns the information structure associated with this named file, the Fstat function obtains information about the file that has been opened on the descriptor fields, and the Lstat function is similar to stat

In the simplest case, diff compares the contents of two files (source and destination files). The file name can be-text read by the standard input device. As a special case, diff--Compare a standard input to its own copy if the source file is a directory and the destination file is not (a di

The diff command is a very important tool on Linux to compare the contents of a file, especially to compare two different versions of a file to find where it was changed. Diff prints changes to each row on the command line. The latest version of diff also supports binary files. The diff program's output is called a pat
In Unix systems, you can use many methods to maintain the source code version. Of course, the most common method is the well-known CVs, but in fact, simple version maintenance does not need to use complex CVs and other specialized version maintenance tools. The diff and patch tools in the UNIX standard can completely back up and upgrade the code.
Diff compares two text files (or directory comparison) in t

The diff command compares a given two files in the simplest case. If you use "-" instead of the "file" parameter, the content to be compared will come from standard input. The diff command compares the similarities and differences of text files in a row-by-line manner. If the command specifies a comparison of the directory, the file with the same file name in the directory will be compared without any compa

Preface Diff is a very important tool program for UNIX systems.It is used to compare the differences of two text files and is one of the cornerstones of code versioning. At the command line, you enter: Diff will tell you what the difference is between the two files.
Objective:
Redis has been used for a long time, basically in the command line aspect, later found that in addition to the command line also provides some graphical monitoring, you can visually see the Redis each instance of a use case.
Here are some common plugins that you can use to monitor Redis:
1, Redis-stat
2, Redis-live
3, Redis-faina
4, Redis-broswer
Here, just pick Redis-stat to record the notes:
