ATI's Perl Programming Course

Summary: 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 Course Outline: CHAPTER 1: A PERL TUTORIAL What is Perl? Where can I get Perl The first Perl program Simple I/O Perl variables Numbers Arrays Array functions Arrays and STDIN Control flow constructs Altering loop control flow Labeled Blocks for long breaks Statement modifiers What is true and what is false Associative arrays The special built in variable - $_ Pattern matching and w/ regular expressions Writing your own functions CHAPTER 2: I/O IN PERL Introduction The print function The printf function The sprintf function Filehandles Opening disk files File open errors Closing files Opening pipe files Command line arguments File operators The stat operator The _ filehandle CHAPTER 3: PERL OPERATORS Introduction Table of Perl operators Assignment operators Special String operators Relation operators Logical operators Arithmetic operators The conditional expression The range operator Regular expression operators String operators CHAPTER 4: ARRAYS + ARRAY FUNCTIONS Introduction Assigning values to an array Subscripting Array functions push and pop shift sort, reverse, chop split, join splice Associative arrays Associative array functions Associative array example Built in associative arrays Reading from a file into an associative array CHAPTER 5: SUBROUTINES Subroutines Passing arguments to subroutines Returning values The require function @INC Packages Modules and use Typeglobs Predefined subroutines CHAPTER 6: DATA STRUCTURES References Higher Dimensional Arrays Complex Hashes References and Subroutines Linked Lists CHAPTER 7: ACCESSING SYSTEM RESOURCES Introduction File and directory system calls mkdir, chdir, and chown Opendir and readdir Link, unlink, rename Time stamps for disk files - stat and utime Process creation - fork exec and wait signals system CHAPTER 8: ODDS AND ENDS eval warn quoting Sorting with custom comparison functions here strings tr pack and unpack Regular Expressions Command Line Options Debugging The strict.pm module The -w flag The Perl debugger CHAPTER 9: GENERATING REPORTS WITH PERL Introduction Formats Multi-Line formats Filled Field formats Top of Page formatting The select operator Special Format Variables: $~, $^ A sample report generator CHAPTER 10: CLIENT/SERVER APPLICATION USING TCP/IP Introduction Internetworking with TCP/IP Client/Server applications Perl functions for networking applications A simple client/server application Code for the client program Code for the server program Client/Server Programming using Socket.pm CHAPTER 11: A CGI PRIMER Introduction A typical form Web Servers & Web Clients HTML & HTML form tags CGI Input GET methods CGI Output Environment Variables Decoding form data CHAPTER 12: MODULES & OBJECT ORIENTED PROGRAMMING Perl Modules included with the distribution What is CPAN?
