Hello World Script



start with the program starting with 90% of Perl programmers, the "
Hello World!
." The idea is simple: make print that phrase on the screen.
In this program we use an integrated feature called

print (), which sends output to a specific location. In this case such location is the standard output

(STDOUT

), ie the screen.

To start take the template and fill it with our information such as name, version, date, author and description. Once you have that will save the file as
Hello.pl
. This is a very simple, containing only one line of code.

# / usr / bin / perl-w




#--------------------

# Script Name: Hello.pl


# Script Version: 1.0
# Date: 26.08.2007
# Author: goblin
# Description: Prints "Hello World!"
screen # Revision History:

# 1.0 / : original version
#-------------------- print " Hello World \\ n ";
In future articles will explain the character
\\ n , along with others like him. Represents a line break character and makes the cursor is placed in the following line to run the program. To find the difference tested with and without it.
Now, to run the program, we must do the following:

UNIX : First of all we must make the file executable. This is done with chmod 755 Hello.pl
or chmod + x Hello.pl . For more information on chmod type man chmod . Now we can run with
. / Hello.pl . Windows



: perl Hello.pl Mac OS : Drag the file and drop Hello.pl
MacPerl the icon, then select Run Hello.pl
from the Script menu. Those

you program in other languages \u200b\u200bmay have noticed that we do not use parentheses () with the "print ()." In Perl you can use or not, our choice.
• Now that we have our first program we will modify it a little more interesting. We will make a script that we asked for the name, process the response and return a result to the screen. In this case we use a new feature called chomp (), which removes a newline at the end of a string. By accepting input from the command line, the (character) return to the user pressed is also stored in the string. Using chomp, we remove this extra newline character and focus solely on alphanumeric data input.
  
Perl also has a feature called
• chop () that removes the last character of a string. Unlike
chomp ()
• , chop () removes any character whatever, while
chomp () removes

only if it is a newline. As always we need to remove only a newline is safer to use
chomp ()
.
The first will be to user data. The way to do this is to print some text on the screen to request the name and then read what the user enters, keeping it in a variable. This information, which is viewed through standard input (STDIN

), you can easily apply chomp function. As this information is in a variable, it is also easy to reuse that variable to our print instruction. # / usr / bin / perl #----------------- # Script Name: Hello.pl # Script Version: 2.0 # Date: 26.08.2007
# Author: goblin
# Description: Prompts user for name, strips of newline character # and prints "Hello !" screen WHERE name = the whole text.
# Revision History:
# 1.0: original
# version 2.0: added prompt for user's name and returned text based on it.
#-----------------
# ask user for name
print "What is your name?"
$ input =
;
# remove newline character
chomp ($ input);
# print results to page
print "Hello $ input! \\ n";



see that you can use $ input
within quotes function print. If we had used single quotes would have sent "$ input" literally to the screen.

Now try your program and if you have any doubts leave it in the comments.

Like with the Manual of Perl, I will start a series of articles to learn the language of SQL databases. It is a very basic manual aimed at those who do not have knowledge about it or a very basic knowledge. I appreciate any suggestions or corrections. Introduction
SQL stands for Structured Query Language , language communication standard widely used databases. Some of its features is the saving of time, flexibility and security in the maintenance of data. Most
management systems modern relational databases like MySQL , MS SQL Server, Microsoft Access, MSDE, Oracle, DB2, Sybase, Postgres and Informix use SQL as a language standard. Despite being used by major RDBMS , each of which implements specific functions which need not necessarily work in others.
This manual will explain the most common SQL commands and how to apply on the basis of known data.

(I): Introduction to German law outlawing

Germany is the first European country to introduce tougher laws in this country, laws that will prevent (or so he thinks the government) hacker activities. The so-called Anti-hacking Law

said that create or own security tools that could potentially be used in attacks is prohibited.

Some amendments of this law clearly defines that even a local attack

Denial of Service (against an application) will be considered a crime. "Hackers" - which in his opinion - are the people who commit such attacks, could be sentenced to more than 10 years in prison. Controversy is the best word to describe what goes through the head of security professionals from Germany, who do not know whether they do or do not work. For example, create and own tools, as this can be used for various purposes ...

is, not tools can be used to run tests on a network, as these can cause a Denial of Service (DoS) and that password crackers or talk. The fact is that, by law, any security company will be committing an illegality, as in analyzing a network are using a port scanner. This clearly shows that the German government did not take into account the views of these professionals.

security consultants expect some modifications, such as those in the law of "computer misuse" in the UK. Many security-related groups are removing the tools that may be related to this law, as in the group "The Hackers Choice

, or are moving to Holland, as the creators of KisMAC (a network sniffer) on its website reads" German says: Good-bye KisMAC ! "
But what tools can be used to hack?

Your browser (you can use to exploit flaws in Web applications). Or just a console terminal telnet ... ... ... vi ... notepad?

For many drivers do not need any other tool to invade a system.

The Chaos Computer Club

(respected German hacker group) summarizes the situation: " seems that German politicians have now decided that the country is free of security problems
. " That with his pen and his total lack of knowledge created another stupid law that will not solve any problem
.
And the security companies? or close or be "criminal" ...
