Course content

1 section • 12 lectures • 1h 1m total length

  • Introduction4:26

    Explore Perl, a flexible scripting language that processes large amounts of text and generates web pages. Understand how server-side execution differs from client-side scripts delivered to your browser.

  • Hello world6:17

    Perl programming basics teach hello world printing to the screen by using dollar-sign variables for X and Y, whose values one and two are displayed.

  • Operators5:05

    Explore basic operators in Perl programming, including addition, subtraction, multiplication, and division. Practice evaluating expressions and printing results to the screen to understand operator behavior.

  • Conditionals4:09

    Explore conditionals in Perl programming, focusing on how the condition becomes true and the subsequent statement executes, with examples like numbers greater than zero and printing results.

  • Array4:19

    Explore the basics of arrays in perl, focusing on indexing and retrieving data by index. Learn to print values to the screen and understand static indexing in practice.

  • For loop5:30

    Explore how to use a for loop in Perl to process elements, initialize with zero, increment values, and print to the screen.

  • Array Operation6:02

    Learn array operations in perl by sorting values with a function, producing ascending and descending orders, and working with records and data to illustrate practical sorting techniques.

  • Push-Pop Array6:38

    Learn how to manipulate arrays in Perl programming by pushing and inserting elements, then removing from the left or right, with results printed to the screen.

  • Array Function5:52

    Explore using the array function in Perl, including map, to transform each element and produce results like doubling values, printing outputs, and applying conditions.

  • String Function5:05

    Explore Perl string functions for transforming text, including converting to uppercase and lowercase, and capitalizing the first letter, using single-argument calls on variable values.

  • String Functions - 23:54

    Explore Perl string functions by using length to determine string size and substr to extract substrings with a start position and optional length, demonstrated through practical examples.

  • Comments4:04

    Learn how comments clarify code and how an if statement uses x and y values to change the screen color when a condition is true, while comments remain unseen.

Description

Perl is a well-established programming language that has been developed through the time and effort of countless free software programmers into an immensely powerful tool that can be used on practically every operating system in the world.

The Perl languages borrow features from other programming languages including C, shell script (sh), AWK, and sed; They provide text processing facilities without the arbitrary data-length limits of many contemporary Unix command line tools.[15] Perl 5 gained widespread popularity in the late 1990s as a CGI scripting language, in part due to its unsurpassed regular expression and string parsing abilities.

In addition to CGI, Perl 5 is used for system administration, network programming, finance, bioinformatics, and other applications, such as for GUIs. It has been nicknamed "the Swiss Army chainsaw of scripting languages" because of its flexibility and power, and also its ugliness. In 1998, it was also referred to as the "duct tape that holds the Internet together," in reference to both its ubiquitous use as a glue language and its perceived inelegance.

Perl is a highly expressive programming language: source code for a given algorithm can be short and highly compressible.

different purposes but developed for use in multiple applications. For those just delving into the world of programming, this can be a little overwhelming. Luckily, there are plenty of languages that are simple to learn, highly versatile to use, and make a great starting point for gaining fluency in the coding universe. Perl is one of those languages, and this course will teach you everything you need to know.

Perfect Perl the Easy Way

  • Work with different data types including strings, numbers, variables and user input

  • Create and use array, subroutines, hashes, and regular expressions in Perl applications

  • Gain a conceptual understanding and practical skills to construct your own levels

  • Become competent with the Perl language family and its use in various applications

  • Prepare a foundation of knowledge for learning other more complex languages.
