Development Environment In GNU/Linux In the work environment, virtual machines are a major issue. Therefore, we will introduce them separately before this chapter. In addition to virtual machines, there are several important things, including the editor, compiler, and the automation tool GNU make.Many working in Linux use VI or Emacs as the editor. If you are interested in trying, I suggest you do not give

access statistics from search engines: it is a very effective data source for user behavior analysis. With the development of the Internet over the years, WEB Log statistics tools have become more and more mature and feature-rich. Many of them are open source code, and AWStats is an excellent one.AWStats: Advanced Web Statistics AWStats is a fast-growing Perl-based WEB log analysis tool on Sourceforge. Compared With Webalizer, an excellent open-source log analysis tool, AWStats has the followin

The support and developers of the GNU program, especially Richard Stallman, refer to a Unix-like operating system called Linux as GNU/Linux. Linux is not a complete operating system, but a Unix-like kernel. It was developed by Linus Torvalds and others. The first version was released in 1991. The GNU program started in 1984 with the goal of completing a comple

The GNU program, also known as the slave program, was publicly launched by Richard Stallman on September 27, 1983. Its goal is to create a set of completely free operating Systems. It has made a standard for the GNU C when writing Linux. ANSI American national standards association, the standard ANSI C standard that it made to C was later accepted by the International Standards Association as standard C so

For example, myprog-U "Arnold, Joe, Jane" (separated by commas); myprog-U "Arnold Joe Jane" (separated by blank characters) The option should appear on the command line before the operand. The getopt () force option of the UNIX version complies with this Convention. The getopt () of the GNU version does not have this Convention by default,

Recently, I am taking an online Lab Course to extract the text. The teacher asked me to use dom-tree for extraction. We need to extract HTML and convert it into XML, I am not learning gnu c programming. I just want to write it myself. It seems that HTML conversion to XML is not a matter of one or two days. I just want to know if there are any tools, the technology is quite frustrating), and suddenly found an artifact-HTML tidy. This software can help

A regular expression is a logical formula for string operations. It uses predefined characters and combinations of these specific characters to form a "rule string ", this "rule string" is used to express a filtering logic for strings.Given a regular expression and another string, we can achieve the following goals:1. Whether the given string conforms to the filtering logic of the regular expression (called "match ");2. You can use a regular expression to obtain the
