File and Directory Commands in Ubuntu System

cd

The cd command changes directories. When you open a terminal you will be in your home directory. To move around the file system you will use cd.

• To navigate into the root directory, type:
  

  cd /

  
  
• To navigate to your home directory, type:
  

  cd

  or
  

  cd ~

  	The ~ character represents the current user's home directory. As seen above, cd ~ is equivalent to cd /home/username/. However, when running a command as root (using sudo, for example), ~ points instead to /root. When running a command with sudo, the full path to your home directory must be given.

• To navigate up one directory level, type:
  

  cd ..

  
  
• To navigate to the previous directory (or back), type:
  

  cd -

  
  
• To navigate through multiple levels of directories at once, specify the full directory path that you want to go to. For example, type:
  

  cd /var/www

  to go directly to the /www subdirectory of /var/. As another example, type:
  

  cd ~/Desktop

  to move you to the Desktop subdirectory inside your home directory.
  

pwd

The pwd command outputs which directory you are currently located in (pwd stands for “print working directory”). For example, typing

pwd

in the Desktop directory, will show /home/username/Desktop.

ls

The ls command outputs a list of the files in the current directory. For example, typing

ls ~

will show you the files that are in your home directory.
Used with the -l options, ls outputs various other information alongside the filename, such as the current permissions on the file, and the file's owner.

cp

The cp command makes a copy of a file. For example, type:

cp foo bar

to make an exact copy of foo and name it bar. foo will be unchanged.

mv

The mv command moves a file to a different location or will rename a file. Examples are as follows:

mv foo bar

will rename the file foo to bar.

mv foo ~/Desktop

will move the file foo to your Desktop directory but will not rename it.

rm

rm is used to delete files.

rm foo

deletes the file foo from the current directory.
By default, rm will not remove directories. To remove a directory, you must use the -R option. For example,

rm -R foobar

will remove the directory foobar, and all of its contents!

mkdir

The mkdir command allows you to create directories. For example, typing:

mkdir music

will create a directory named music in the current directory.

C#

What is an Abstract Class?

An abstract class is a special kind of class that cannot be instantiated. So the question is why we need a class that cannot be instantiated? An abstract class is only to be sub-classed (inherited from). In other words, it only allows other classes to inherit from it but cannot be instantiated. The advantage is that it enforces certain hierarchies for all the subclasses. In simple words, it is a kind of contract that forces all the subclasses to carry on the same hierarchies or standards.

What is an Interface?

An interface is not a class. It is an entity that is defined by the word Interface. An interface has no implementation; it only has the signature or in other words, just the definition of the methods without the body. As one of the similarities to Abstract class, it is a contract that is used to define hierarchies for all subclasses or it defines specific set of methods and their arguments. The main difference between them is that a class can implement more than one interface but can only inherit from one abstract class. Since C# doesn�t support multiple inheritance, interfaces are used to implement multiple inheritance.

Both Together

When we create an interface, we are basically creating a set of methods without any implementation that must be overridden by the implemented classes. The advantage is that it provides a way for a class to be a part of two classes: one from inheritance hierarchy and one from the interface.

When we create an abstract class, we are creating a base class that might have one or more completed methods but at least one or more methods are left uncompleted and declared abstract. If all the methods of an abstract class are uncompleted then it is same as an interface. The purpose of an abstract class is to provide a base class definition for how a set of derived classes will work and then allow the programmers to fill the implementation in the derived classes.

Type Casting

Converting an expression of a given type into another type is known as type-casting.

Implicit conversion

Implicit conversions do not require any operator. They are automatically performed when a value is copied to a compatible type

short a=2000;

int b;

b=a;



Explicit conversion

C++ is a strong-typed language. Many conversions, specially those that imply a different interpretation of the value, require an explicit conversion.



short a=2000;

int b;

b = (int) a; // c-like cast notation

b = int (a); // functional notation

sealed class

A sealed class cannot be inherited. It is an error to use a sealed class as a base class. Use the sealed modifier in a class declaration to prevent inheritance of the class.

sealed class MyClass

{

public int x;

public int y;

}

Microsoft Dynamics AX

Microsoft Dynamics AX is one of Microsoft’s enterprise resource planning software products.

History

Microsoft Dynamics AX was originally developed as a collaboration between IBM and Damgaard as IBM Axapta. IBM returned all rights in the product to Damgaard shortly after the release of Version 1.5. before Damgaard was merged with Navision Software A/S in 2000. The combined company, initially NavisionDamgaard, later Navision A/S, was then ultimately acquired by the Microsoft Corporation in the summer of 2002.[3] Before the merger, Axapta was initially released in March, 1998 in the Danish and U.S. markets. Today, it is available and supported in forty-five languages in most of the world.

Custom AX development and modification is done with its own IDE, MorphX, and resides in the same client application that a normal day-to-day user would access, thus allowing development to take place on any instance of the client. The development language used in Axapta is X++.

On May 26, 2008, Microsoft completed developing the latest version (2009) in facilities spanning the globe and including sites in Vedbæk, Denmark; Kiev, Ukraine; Fargo, North Dakota, United States; and Redmond, Washington, United States.

Architecture

The Microsoft Dynamics AX software is composed of four major components:

The Database Server, a database that stores the Microsoft Dynamics AX data
The File Server, a folder containing the Microsoft Dynamics AX application files
The Application Object Server(s) (AOS), a service that controls all aspects of Microsoft Dynamics AX's operation
The Client(s), the actual user interface into Microsoft Dynamics AX

 

MorphX and X++

MorphX is an integrated development environment in Microsoft Dynamics AX that allows developers to graphically design data types, base enumerations, tables, queries, forms, menus and reports. MorphX supports drag-and-drop and is very intuitive. It also allows access to any application classes that are available in the application, by launching the X++ code editor.

Because MorphX uses referencing to link objects together, changes in, for example, datatypes of fieldnames will automatically be reflected in all places where they are used (such as forms or reports). Furthermore, changes made through MorphX will be reflected in the application immediately after compilation.

Microsoft Dynamics AX also offers support for version control systems (VCS) integrated with the IDE, allowing collaboration in development. There is also a tool for reverse-engineering table structures and class structures to Visio. The actual implementation limits the practical use of both these features.

X++ itself is the programming language behind MorphX, and belongs to the curly brackets and .-operator class of programming languages (like C# or Java). It is an object-oriented class-based single dispatch language. X++ is a derivative of C++ (both lack the finally keyword for example) to which garbage collection and language integrated SQL queries were added.
