Problem Description:
Project 5.2 Page 198
The first exercise involved interaction with the user in the form of giving the user instructions to enter five parameters, the positional parameters are used here and the user is prompted to enter the correct number of arguments.
The first terminal window is my script, displayed by typing "cat Project5-2".
The second and third screen show two consecutive runs of the script, one with insufficient argument and another with correct arguments.
Project 6-2 (page 245)
This assignment illustrated the proper use of the "case" statement. The "case" statement allows a conditional expression to be evaluated based on pattern-matching. "Case" is similar to an if-then-else clause, except that a "case" statement uses fewer lines of code.
The first terminal window is my script, displayed by typing "cat Project6.2".
Next five screens show three consecutive runs of the script by passing various number of parameters.
(a) With 0 parameter
(b) 1 parameter
With 2 parameters
(d) With 3 parameters
(e) With unspecified parameters
The second exercise was a continuation of the first exercise in interacting with the user.
Similar to the first exercise, an instruction was given to the user. This time, however, the user was asked to input his or her name, as there were no items to pick from a list.
The name entered by the user was compared to my name, and an appropriate response was echoed to the user, depending on the results of the comparison.
The first terminal window is my script, displayed by typing "cat scriptname".
The second terminal windows is two consecutive runs of my script. The first run uses a random name, while the second run uses my name as input.
In each case, an appropriate output is displayed. Read More

Practical UNIX Security

However, these modules require frequent updates for virus definitions and new threats, which may affect the network anytime. Every now and then, new threats are designed and developed by hackers or cyber criminals. In spite of securing the networks and data centers, with the most updated and advanced security modules, there is still a probability of a new threat to intrude into the network. In addition, hackers and cyber criminals are exploring efficient codes day by day to improve the hacking software, in order to breach in to classified information, banks, online websites etc. As the threats and vulnerabilities are infinite, no one can memorize them in order to take a measured approach, the initial step is to identify the vulne...

Practical UNIX Security

...?Running Head: UNIX Security UNIX Security Unix is the operating system which was foremost developed in 1960s and is under regular development since that time. Operating system can be understood as the group of programs responsible for making the computer work (Peek Jerry, 2002). It is a multi-user, stable, multi tasking system for severs, laptops and desktops. Unix systems are also equipped with graphical user interface in the same way as Microsoft Windows, which gives an easy to use atmosphere. However, knowledge of unix is essential for operating Unix systems as it is not covered by a graphical program, for instance, in telnet session. There are various versions of Unix available however they are slightly different. The most admired...

Linux vs HP-UNIX

... and number] in format: 12 May 2002] Linux vs HP-UNIX UNIX as an operating system is uniquely exceptional through its file system and the ability to coordinate the naming of resources as well as accessing the same resources. An idea was therefore adopted to "design a network-level protocol, called 9P, to enable machines to access files on remote systems." (Pike et al) Bell Labs As UNIX worked toward being a reputable file system and operating system, but, as this type of file system and operating system becomes redundant another more powerful user friendly operating system called Linux. Kernel Many of the new operating systems tend to implement two classes of processes. In the older versions of UNIX (pre- 8 ), these included normal UNIX...

Benign paroyxsmal positional vertigo

... degeneration from the utricular otoliths of the cupula. These particles float freely within the endolymph of the canal instead of being firmly attached to the cupula, and the "heavy conglomerate", which almost fills the canal, is assumed to be the cause of the positioning vertigo. The movement of the conglomerate causes either an ampullofugal or an ampullopetal deflection of the endolymph depending on the direction of the sedimentation. A valid model of the pathophysiology of BPPV must be able to predict the direction, latency, duration and fatigability of the typical nystagmus, as well as changes in these parameters due to other head manoeuvres. Liberatory Manoeuvre: The efficacy of positioning or liberatory manoeuvres of the head can...

File management in UNIX

...File management in UNIX A UNIX file system is a method of managing large amounts of data by storing and organizing them in a chronological manner (Pfleeger et al, 2003). Also known as file access rights, file protection on the other hand is a system that allows a user to create a file that has restricted access to only a few selected people. Editing abilities, which involves write and delete privileges are normally the same in a UNIX system since it allows one to overwrite a file with a different one. An individual who creates a file is considered the owner and thus has the sole permission to manage that file (Garfinkel, et al, 2003). The owner therefore is the only person who can change the protection system of that particular file...
