Perl Programming on UNIX

Request more details:

Description:
Perl has been described as C, awk, sed, and shell programming all wrapped into one language. In this intense, 5-day, hands-on programming course, you will learn how to take advantage of Perl`s power through examples and extensive exercises. Arrays and hashes, I/O, regular expressions, subroutines, and complex data structures are covered in depth. The course also introduces object-oriented programming in Perl, as well as UNIX multi-tasking and Perl sockets programming.
Prerequisites:
Fundamentals of UNIX. Experience in a high-level programming language, such as C, C++, or Java, is strongly recommended.
