Why use Perl?
Perl's syntax is similar to C and shell scripts, but it has its own unique features, such as strong regular expression support, flexible variable types and scopes, built-in hash tables, etc. Perl also has a large number of built-in functions and modules, which makes Perl programming very efficient and convenient.
Perl is widely used in text processing, for example, Perl can easily extract data from text files, process XML and HTML documents, manipulate databases, and so on. In addition, Perl is also widely used in network programming and system administration. For example, Perl can write scripts to manage servers, execute system commands, send e-mail, and so on.
Although Perl has lost its place in Web application development to languages such as Java, PHP, and Python, it is still a very useful language in the areas of text processing and system administration.
