Code-Maven series

If you are a beginner, or would like to refresh your Perl programming knowledge, you can go over the Perl tutorial or watch the Beginner Perl Maven video course.

If you need to maintain a large piece of software written in Perl by other people in the last 5-10-15 years, that's a challenge. Especially if you did not get proper training in Perl. You are probably limited to a specific and old version of Perl. Check out, the Perl tutorial! You can probably skip the part about installing Perl, but the rest of the tutorial will be relevant for you.

Perl is often used in Test Automation. If you work in this field, or if you'd like to work in this field (it is much more fun to find bugs in other people's code than in yours :), then you can read the Perl tutorial and the series on Test Automation using Perl.

If you build new web applications - either privately or inside a company - you can start by reading the article comparing CGI, mod_perl and PSGI. From there you can go on reading the generic Perl tutorial or the articles on Mojolicious, Perl Dancer, Catalyst, PSGI/Plack, or even CGI, the Common Gateway Interface, for old-school web applications.

In the off chance you are interested in topics other than Perl, especially related to Test Automation, Continuous Integration, Continuous Deployment, DevOps, then you are welcome to check out the list of DevOps related training courses.

Get absolute path (aka. canonical path) using abs_path or canonpath

It is often a good idea to have your configuration files or your code contain relative pathes to various locations as that makes it easy to install your application in different places.

It also makes it a lot easier to run two totally separate copies of the same program on the same machine.

However, when accessing the files it is often better to use the absolute path-es.

So the question arises: How can you convert a relative path to an absolute path?

tell how far have we read a file

In very rare cases you might need very some very fine-tuned file reading operations in which after reading some part of a file you might need to re-read that part, or you might need to jump over large sections of a file. The two tools for this are tell and seek.

tell can, well, tell you the current position of the filehandle. How far are the reader head from the beginning of the file.

seek can move the current position of the filehandle very fast.
