Maintenance function of 1.Unix system
As we said earlier, Perl can be used as an alternative to traditional UNIX system maintenance tools, and in this context it can operate on text files, especially configuration files (which also remember how to configure text in a Linux system).
2. CGI Scripts
One of the most important functions of Perl is to write CGI applications. Because the interaction on the web is primarily a textual interaction, Perl has a unique advantage in this regard. That's why we chose Perl as a writing CGI program.
3. Automated mail handling and FTP functions
One other use of Perl is to automatically process mail. You can use Perl scripts to filter the letterhead based on the address or content. Perl itself can also automatically write a mailing list. At the same time, Perl can also be used to write FTP client programs, so that remote access to file automation.
4. Web site Maintenance Automation
Perl can automate the maintenance of your Web site. Because a Web page is just a text file with a special format, Perl can handle these pages with its powerful text processing capabilities. At the same time, Perl has the ability to communicate with TCP/IP, which allows Perl to maintain the site remotely.
5. Database processing
Since the Perl language has a large number of extensions that can be used to communicate directly with a variety of mainstream databases, with its powerful textual capabilities, the Perl language can be designed to be one of the foreground handlers for the most commonly used database on a Web site.
