The UNIX operating system utilized by our company, XYZ Corporation




(Include appropriate APA running header with page number, Paper should meet APA guidelines);Executive Summary;(Separate Page ? to the non-technical CEO, manager, etc);The UNIX operating system utilized by our company, XYZ Corporation, is responsible;for supporting 350 employees as well as 6,000 customers. Our Apache web site is visited by;1,345 Internet users daily. This makes our UNIX infrastructure the most important company;asset we have. As the systems manager, it is my responsibility to maintain a stable operating;system that is available and responsive every minute of every day. For this reason, I am;proposing funds to write a shell script that will expedite the process for finding various files and;character strings regardless of their location in the UNIX file system structure. This particular;script will save the systems administration department two hours of productive time each day.;The additional 10 hours each week can be used by the systems administration team to provide;even better employee and customer service for our users and web site visitors. The cost for;developing this script is $350.00. The pay back period for this expense is one week. I am;requesting permission to dedicate one assistant administrator for 10 hours to this project.;Introduction;(Separate Page ? to the technical director, manager, etc.);The systems administration department spends 2 hours each day searching for files by;content, or by file name, for employees who have archived information on our storage area;network (SAN). In order to expedite the time it takes the staff to perform a search and to inform;the user of the results, I am proposing funding to dedicate one assistant administrator to write a;Bourne Again Shell (bash) script that will automate this task. The shell is the command line;interpreter for the UNIX kernel (Das, 2001, p.3). This particular bash shell script will group all;the commands used by an administrator during a file search task into a single executable file. The;ability to string together a whole group of commands as a language ?with its own variables;conditionals, and loops ?is know as scripting (Das, 2001, 535). This paper introduces our shell;script and explains how it will reduce costs and improve productivity in the systems;administration department.;Body;(Separate Page ? describe each line of commands making up your script);This section provides a line-by-line explanation for our proposed bash script. By;presenting a line-by-line description, our analysis follows the interpretive mode used by the shell;of interpreting one statement at a time in a script (Das, 2001, p.535). The entire script can be;viewed in its entirety in the appendix. Although the script is presented as a written, final product;it has not been executed or tested for bugs on our particular system. This process will take the;proposed 10 hours of time and must be performed during a week-end when the system is not;being utilized.;#!/bin/bash;This statement is required as the first interpreted line in a shell script. It is used to inform;the kernel on which shell to use when interpreting the script. The # is normally treated as a;comment line. When it is followed by the !, the shell interprets the remainder of the string as the;interpreter specification (Das, 2001, p.539).;PN=`basemane ?$0?`;This statement assigns a value to the variable PN. Shell variables are a convenient way of;storing values that can be used throughout the rest of the shell script (Das, 2001, p.536). The tick;marks, `, will execute a shell command, and in this statement, store the results in the variable;named PN. The basename command is used to change a filename extension (Das, 2001, p.572).;When basename is used with a second argument, it strips off the string represented by the;argument from the first argument, $0 (Das, 2001, p.572). For example, if the first argument ($0);on the command line is Linux Verison 2.4, the basename will strip off the Version 2.4 and leave;only the word ?Linux.?;Include appropriate APA running header with page number, Paper should meet APA guidelines);Continue with each line of your script until you complete the body section & be sure to;cite your references ? 3 to 5 pages describing each line of your script.;(Include appropriate APA running header with page number, Paper should meet APA guidelines);Conclusion;(Separate Page ? this is where you have a dynamic closing statement);Write a closing conclusion for your paper ? reiterate how your script will benefit the;company.;(Include appropriate APA running header with page number, Paper should meet APA guidelines);Appendix;(Separate Page ? include the original shell script you wrote);Shell Script;(place you actual shell script here so I can read it before grading your paper).;bin/sh;# script written for FreeBSD 5.4-STABLE;# written by B.
