Perl is a popular language in the scripting community. You can use Perl to supercharge your scripts, to perform tasks such as complex string manipulation, regular expression matching, file I/O, and so on. You can also use Perl to implement Web applications and to access data in relational databases.
This course covers all these techniques, and also shows how to write object-orientated Perl code to help structure larger solutions.
What you'll learn:
Understanding Perl syntax and data types
Using Perl collections
Working with subroutines
Using strings and regular expressions
Manipulating files and XML/JSON data
Developing Web applications using CGI
Accessing databases using DBI
Prerequisites:
Familiarity with another scripting language such as bash or ksh, or experience with a high level language such as C or Fortran
