Description
Perl is a powerful high-level programming language developed for the purpose of text handling. However, today it is applied for several activities including web development, Bioinformatics, system administration, GUI development, games and network programming. Perl 5 has got immense popularity in the late 1990s in the form of a CGI scripting language. This can also be attributed to its great regular expression and string parsing abilities.
Benefits
- Perl consists of the features of various programming languages including C, awk, sed, etc., thus making it more useful and productive.
- Perl makes the work of system administration simple because of having various scripting language capabilities.
- You needn’t rely on several languages; you can simply use Perl to perform the entire task of system administration.
- Besides, Perl is also applied in web programming, GUI programming, web automation etc.
- Perl can be embedded within web servers so as to raise its processing power. It also consists of DBI package, which leads to efficient web-database integration.
- The file operations and regular expressions are amazing in Perl.
- It was built by Larry Wall who was essentially a linguist, so you can expect good support for text operations. PCRE (Perl Compatible Regular Expressions) are also applied in PHP.
