AIX (Advanced Interactive eXecutive) is an operating system developed by IBM for business all across the world that needs data metrics that can keep up with the ever-changing scope of business in today’s world. AIX is a version of UNIX. AIX is designed to work on a number of computer platforms from the same manufacturer. On its launch, the system was designed for IBM’s RT PC RISC workstation.
AIX was developed with Bourne Shell
as the default shell for three versions of the OS. Afterwards, it was changed
to KornShell going forward from version 4. The OS uses Common Desktop
Environment (CDE) as the default user interface for graphics. The System
Management Interface Tool on the OS allows users to access the menu using a
hierarchy of commands instead of the command line.
The operating system works on a number of hardware platforms. The initial OS was designed for the IBM RT PC and used a microkernel that controlled the mouse, disk drives, keyboard, and display. This allowed users to use all these components between operating systems by the use of a hot key-the alt+tab combination. The OS was also fitted on newer systems such as the IBM PS/2 series, IDM mainframes, AI-64 systems and can also be used with the Apple’s server network. AIX is commonly used on IBM’s 64-bit POWER processor and systems. AIX can run most Linux applications (after recompiling) and has full support for Java 2.
Since its introduction to computer infrastructure, the operating system has undergone a lot of upgrades with five versions released since 2001. The latest version of the software is the AIX 7.2. All of these come with a high tech security system and fast uptimes.
As an operating system AIX has become popular with students who learn quickly by working on AIX projects live. Working professionals have also been attracted by the dependability of the system and the intuitive that is part of its design.
Do you think that the command lines are an old-fashion
leftover from previous decades or an antiquated way of using a PC?
Think again. Indeed, it is one of the most powerful and flexible ways
to perform and manage in Linux. If you come from the comfort of a Mac
or Window desktop, however, it can be a bit intimidating to get used to
Linux commands. Everything is secretive, dark, and anything but
friendly to beginners. That’s why we have rounded up this short list of
the most useful Linux commands with examples. Keep reading and speed up
your learning journey with Linux.
1. Ls command – list files
is one of the most basic and common commands in Linux. You can use it
to print contents in the current working directory and see the list of
files, directories, or folders on your Linux system. For instance,
the command “ls tourism” will display the users every folder store
inside the overall “tourism” folder. Keep in mind that directories and
files will be denoted in different colors, which can be selected in the
system. You would also use the command “ls – R” to display all
files both in the directories and subdirectories. Since Linux commands
are case sensitive, make sure to enter “R” instead of “r” to avoid an
2. Cat command – create and view files
use the “cat” command to show text files. Also, it would be used for
creating, combining, and copying text files. For example, use “cat
linux_tip” to get inside the linux_tip file and read its contents on
the screen. To combine two text files “linux_tip_1” and
“linux_tip_2, you can enter the following command “cat linux_tip_1
linux_tip_2 > linux_tip”. Keep in mind that only text documents
would be combined and shown with this command.
3. Rm command – delete files
“Rm” command can be used for removing files or directories from your
Linux system without confirmation. The syntax is simple “Rm
name_deleted_file.” For example, the command “rm computer_science”
will immediately remove the file or directory named “computer_science”
from your computer. Make sure to consider carefully before using this
command because you cannot get it back.
4. Mv command – move and rename files
To move and rename files, the “mv” command will be used. Here is the basic syntax for this task: “mv filename new_location.” Suppose
that you need to move the file name “english_class” to location
“/home/school/documents”, just enter the command “mv english_class
/home/school/documents.” Keep in mind that this command requires the
permission of users. The syntax for renaming a file is “mv filename newname”. An example command is “mv english_class french_class”
5. Mkdir – create directories
you want to create a new directory in your Linux system, then you can
use the “mkdir” command. The syntax is “mkdir new_directory.” For
instance, you can create a new directory named “final homework” by
typing the following command “mkdir final_homework.” In case you do not
want to make a parent directory manually, add the -p argument. Keep in
mind that it is -p, not -P. Everything in Linux is case sensitive.
6. Rmdir command – remove directories
contrast with the mkdir command, you can use the rmdir command to
remove a directory. The syntax is similar: “rmdir removed_directory.” If
you enter the following command “rmdir basketball_data”, it will
immediately delete the directory named “basketball_data”. Always check
carefully to make sure that there is no sub-directory or file under the
deleted directory. If possible, it is always better to delete the
sub-directory or files first before moving to the parent one.
7. Man command – seek help in Linux
simply stands for manual. You can use this command to access a
reference book of the Linux system, which is quite similar to the
“Help” file in many popular applications or software. To seek help on
any commands that you don’t understand, just enter “ma command_name”.
The terminal will open a manual page for the typed command. For example, if you enter “man ls”, the terminal will provide you with basic information on the “ls” command.
8. History command – view previous commands
As you can guess from the name, the “history” command can be used to display all of the commands that you just used previously for the current session. This can be helpful in referring to the old commands and re-entering or re-using them in the next operations.
