ATI's Perl Programming Course


Share |

Summary:

    Technical Training Short On Site Course Quote

      Perl is a scripting language which allows for rapid prototyping of projects formerly done with a programming language or a shell. It incorporates all the functionality of C (including a UNIX system interface), the Shells, grep, sed, and awk. The topics in the course will aid all computer users - from end user to programmer to administrator alike. Many in class labs support the course material.

    Prerequisites:

      Some experience with either a programming language (preferably C), or any of the UNIX shells.

    Who Should Attend:

      Programmers, end users, system administrators, network administrators, CGI script writers, or anybody who is interested in automating tasks but doesn't want to learn all the details of a full blown programming language.

    Benefits of Attendance:

      Students will be able to write Perl scripts that:

      • Manipulate files and directories
      • Use the powerful regular expression capabilites of Perl
      • Generate awk like reports
      • Solve problems by using Perl's associative array capabilites
      • Take Advantage of Perl's powerful interface to UNIX and other Oses
      • Perform network communication including those tasks accomplished through CGI programming
      • Perform many system administration functions
      • Be able to use Perl to write CGI applications
      • Be able to use Modules from the Standard Perl distribution
      • Use Perl data structures and references
      • Use object orientation in Perl
      • Create objects and reuse classes
