Perl print how to#

Perl - Environmentīefore we start writing our Perl programs, let's understand how to setup our Perl environment. It is somewhere in between, along with Python and awk and Emacs. It is also not like most versions of C or C++, which are compiled directly into a machine dependent format. So it is not quite the same as shells, or Tcl, which are strictly interpreted without an intermediate representation. When you run a Perl program, it's first compiled into a byte code, which is then converted ( as the program runs) into machine instructions. Traditional compilers convert programs into machine language. Perl is an interpreted language, which means that your code can be run as is, without a compilation stage that creates a non portable executable program. Perl's DBI package makes web-database integration easy. Perl's mod_perl allows the Apache web server to embed a Perl interpreter. Perl can be embedded into web servers to speed up processing by as much as 2000%. Perl can handle encrypted Web data, including e-commerce transactions. Perl is widely known as ' the duct-tape of the Internet'. Perl used to be the most popular web programming language due to its text manipulation capabilities and rapid development cycle. The Perl interpreter can be embedded into other systems.
