HP Perl Programming (H4311)

In this course, provides you will learn the basics of Perl programming, including Perl program syntax and structure, control and data structures, file processing, and use of pattern matching. You will gain the skills needed for system administration with Perl (e.g. running system commands and checking return codes), creating functions, processing fixed-width or binary files, importing and using modules (including object-oriented modules), and programming CGI. You will spend 60 percent of class using HP servers in hands-on labs.

What You'll Learn

  • Use Perl modules, such as Sockets
  • Write basic Common Gateway Interface (CGI) programs that are secure
  • Maintain Perl scripts already in use in your environment
  • Create and run a Perl program, saving time and increasing productivity by automating administrative tasks
  • Improve control over basic system and user tasks
  • Create comprehensive and useful Perl utilities that can dramatically aid in troubleshooting and administrative tasks
  • Read and maintain existing Perl scripts
  • Create and execute a Perl program
  • Use looping and branching statements
  • Use lists, arrays, and hashes
  • Use regular expressions
  • Execute system commands from within a Perl script
  • Use subroutines to modularize programs
  • Use references to implement advanced data structures
