In fact, this is because the email failed to be sent, and sendmail rolled back the email. Check/var/log/maillog: Aug 1 18:41:40 localhost sendmail [5279]: o71Afeih005279: from = root, size = 220

apply what you have learned on a daily basis to promote learning.First, describe diff and patch. All options in the man online document will not be described here, which is unnecessary. In the 99% period, we only use a few options. Therefore, you must learn these options.1.

Linux uses the patch and diff commands to create a file patch. Because during the u-boot porting process, there are several common files to be modified. It is too troublesome to manually modify them each time. Patch creation can solve this problem. The collection of learning materials is relatively simple. The method 1 is similar to this kind of elementary problem. There are a lot of online materials. google or baidu searches for valuable materials an

In fact, it's not just that the vue,react is also required to add the key to each component when performing a list rendering.To explain the role of key, we have to first introduce the Virtual Dom diff algorithm.We know that Vue and react both implement a set of virtual DOM, so that we can render the page without manipulating the DOM elements and simply manipulating the data. And the principle behind it is its efficient

Features of the 1>diff commandThe function of the diff command in Linux is to compare two text files on a line-by-row basis, listing their differences. It checks the given file for a system and displays all the different rows in the two files without requiring the file to be sorted beforehand.2> syntaxdiff [Options] file1 file2The command tells the user which rows to modify in order to make the two files Fi

SVN diff Replacement tool One. Replace SVN diff with Vimdiff: For most Linux developers, Vimdiff's presentation of file differences is obviously much more intuitive than SVN diff. So can we use Vimdiff instead of SVN diff? Fortunately, SVN considered this and supported Third-party programs as contrast differences. No

Using Git in Windows, msysgit is the first choice, but the shell of msysgit is not powerful, the size cannot be changed, and the font is ugly. Therefore, in Windows, using Git in Cygwin is a good choice. Before submitting the code, or merging the code to view the code modification, we often need to diff to see what changes are there, and the diff output is obscure. When there are too many changes, like tian

Usage of git diffThere are three major parts of the Git commit: Working tree, index file, commitof these three parts: Working tree:Is the directory you work in, and whenever you make changes in your code, the state of the working tree changes.Index file: is a working tree and commit bridge, and whenever we use the Git-add command to register, the content of the index file changes, and the index file is synchronized with the working tree.Commit: It's the last stage, only commit, and our code real
