Who should attend: Programmers with previous experience either in a structured programming language, like C, C++, Pascal, Python, or Java, or else in a scripting language like the Bourne shell, Javascript, or Tcl. While some previous exposure to Perl is beneficial, it's not essential.

Designed to be programmer-friendly and platform-neutral, Perl is a high-level, general-purpose programming language that makes easy things easy and hard things possible. Now moving into its second decade, Perl has become the language of choice across all platforms for programmers engaged in rapid prototyping, system utilities, software tools, system management tasks, database access, graphical and Web programming. Perl programming is an essential skill for any system administrator or Web programmer, and an important one for nearly everyone else.

Because Perl incorporates aspects of more than a dozen well-known UNIX tools, experienced UNIX programmers and administrators can come up to speed on Perl very rapidly. However, because Perl is portable to all major platforms, programmers and administrators everywhere will benefit from this high-powered tool.
