What you will learn

Students will learn how to use Perl as a tool to solve problems at work and to enhance their resumes. This course uses a multi-sensory approach to teaching Perl. In other words, you will Hear about Perl in lectures, See Perl in action through live demos, touch Perl by downloading and experimenting with any of the dozens of available program examples, and work with Perl Mentally by going through the exercises.

Description

This course will teach you Perl through a multi-sensory approach.

- You will hear about Perl in lectures.

- You will see Perl work through live examples.

- You will touch Perl physically by working with the dozens of downloadable working Perl programs you will have access to and that are used in the live examples.  You can use these programs to experiment with and as templates for your own Perl programming.

- You will touch Perl mentally by working on the exercises and writing your own Perl programs.

Some of the basic and intermediate level Perl skills you will learn in this course include:

* Downloading and installing Perl on your computer

* Using Perl to work with numbers and strings.  This could be used to do mathematical calculations and to manipulate strings.

* Read data into your programs (for example, .csv files, data from the keyboard, regular files, etc.), detect data patterns, and alter that data with regular expressions and various Perl functions

* Store lists of data in arrays and hashes

* Use subroutines to create larger programs and to break your programs up into manageable pieces

* Access and use ready-made code (modules)

* Create, modify, read, write, and append files.  Combine files, concatenate files.

* Use File Tests to get information that you can use to make decisions about files, much like you'd do as a systems administrator.

* Use References to Create complex data structures (e.g. arrays of arrays, hashes of hashes, hashes of arrays, and arrays of hashes). 

* See all of the above in action and practice what you learn by writing your own programs

Sehr guter Unterricht mit vielen Übungen. Im Untertitel sind zwar oft falsche Wörter, da anscheinend die Sprache automatisch konvertiert wurde, aber das stört nicht so sehr.

This course was exactly what I was hoping for in an intro to Perl class. The instructor knows the subject matter well and does a great job at explaining everything.

Les commentaires sont en Anglais, ce qui me complique la compréhension mais surtout ces commentaires de l'orateurs sont retranscrits en sous titres ... mais ils semblent écrits par un automate qui parfois se trompe de mot !

Overall Learning experience was good. Trainer explanation of each concept is fine. Audio was not clear in some of the videos, Can expect some more content with respect to the course.

I found this course very much interesting. I did not have any knowledge about perl but while doing this course i am finding it very interesting. The teacher is doing great job to make it easy to understand and crisp.

Great course on Perl and the instructor has good teaching style. The only problem is with the small code font size which makes this course very difficult to watch on mobile devices.

This is not someone that I'd have a beer with. He is an interesting individual. That being said, he does introduce Perl very well. I'm inclined to believe that this is the best lecture of Perl on Udemy as of November 2018. I did some research before purchasing this course and am happy that I chose to learn from Darryl. Darryl does well with his explanations. When I found myself confused, I just had to sit through the lecture longer for him to give more in depth explanations. Generally, I am not a fan of powerpoint as this is how I had to learn in school. I prefer hands on exercises... which he did provide at times. However, there will be plenty of powerpoint videos, sometimes followed up by him coding. I wish that Darryl would give more exercises for practice. There was a point where I could no longer do the exercises on my own and needed to watch him complete in order for me to learn. I felt that at those points that I was learning. For me, I had to take a lot of notes with his videos. If you don't, then you may find yourself forgetting much of what you learned (Unless you have plenty of programming experience). He hits crucial topics with Perl, and I'm thankful for this. I believe that once you finish this course, you will be capable of resourcing what you need from here on. Final Edit: The end of the course felt rushed. There needs to be more examples and exercises to solidify an understanding of the material. I ended up removing a half star for this. Final, Final Edit: I appreciate your response Darryl! It's nice that you follow up with students. You don't take offense and can take a hit, I can appreciate that. For everyone else: I am currently reading through "Learning Perl. 5th Edition" by Randal L. Schwartz. If you have missed things in the video lectures here, they are also discussed well in this book. Just seeing things again after having initially been taught by Darryl really helps soak in the information. I am also understanding some content better reading from this book.

Trainer starts with very basic level, so anybody having basic knowledge will pickup very easily. For me first few videos are of no use as I've already worked on Unix/Perl before. Waiting for some more content to come to enhance my skills.

I use windows. I loved the way he first explains it in linux and then windows operating systems covering all students. The lecture was very interactive....loved it.

This course is billed as 'intermediate skill level' but seems to be geared towards people with little to no scripting/coding experience what so ever. Very slow and basic for people that do. However, I will say the instructor is very clear, easy to understand, and comprehensive. The exercises are illustrative and reinforce the delivered content. I would recommend this for people that know some unix basics and are trying to learn perl as their first language.

I could have given more than this rating but there should be more examples added for the operators with small scripts..apart from this good communication and clear explanation is done

I enjoy listening to the speaker. I have no background in Perl but I would be willing to continue the course and see if I can learn something. His examples and follow along helps as I need to see it to understand it. Would not progress as fast with a book, videos really help. Thank you for the course
