What is Perl?

Perl is a programming language to perform tasks that would be difficult or cumbersome on the command line.

Most of the GNU/Linux distributions include Perl by default. Usually, we can invoke Perl using a text editor to write a file and then pass it to the Perl program.

Practical Extraction and Report Language was a language to scan arbitrary text files, extract, and print reports based on that information. Being a good language for many system management tasks, Perl has grown into a general-purpose programming language.

We can locate Perl wherever we choose. However, it’s best for both /usr/bin/perl and /usr/local/bin/perl to be symlinks to the actual binary.

Being popular in demand, Perl has several advantages, which includes:

• Easy to start: It is closer to programming languages like C, C++ and thus, easy to learn.
• Text-Processing: Perl has high text manipulation abilities by which it can generate reports from different text files easily.
• Contains best Features: It contains features of different languages making it more useful and productive.
• System Administration: Since it has different scripting language capabilities Perl makes the task of system administration very easy.
