13. Link of the Week Open Source Software: • http://en.wikipedia.org/wiki/Open_source • http://freshmeat.net • http://sourceforge.net

14. Link of the Week Open Source Software: Definition of Open Source Software. • Available in source code format • Developed in a public, collaborative manner • Software is free of charge • Allows anyone to create modifications of the software, port it to new operating systems and processor architectures Who benefits from open source products?

15. Expected Outcomes Upon successful completion of this course, students will be able to: • Create non-trivial shell scripts. • Perform appropriate UNIX System Administration tasks. • Compose non-trivial scripts using Perl programming language. • Distinguish the roles of Linux and Open Source software. • Incorporate the make utility appropriately within programs. • Create a CGI script

16. Review Shell syntax What is a shell script? A shell script is a script written for the shell, or command line interpreter, of an operating system. It is often considered a simple domain-specific programming language. Typical operations performed by shell scripts include file manipulation, program execution, and printing text.

17. Review Shell syntax • $# - Number of positional parameters • $! - Background PID • $? - Return value • $$ - Process PID • $ - Provides the content of a variable ($NUMBER) • $0, $1, $2, $3 … - The syntax represents the positional parameters on the command line. ./printnum.sh 4 • exit 0 – The return values is a number from 0 to 255. A value of zero (0) indicates a normal exit. • exit 1 - Indicates a failure occurred.

18. Review shell syntax • “ “ - Double quotes. Removes special meaning of all enclosed characters, except $, `, “, and \. • Example: print “The price is $Price.\n”; (interpolation) • ‘ ’ - Literal quotes. Removes the special meaning of all enclosed characters. A single quote cannot appear within single quotes because a single quote denotes the end of the string. • ` ` - Single Back-Tic quotes. Used for command substitution. • Example: echo The date is `date` (interpolation) • LINES=`wc -l $ENTRY | cut -c 1-7` • LISTING=`ls -l | cut -f 9`

19. Review Command Structure • if [ -d "$1" ] then action statement fi • wc –l - Word count with –l (line option). Print the new line counts • ~ - Tilde (~ means /home/dandrear) • for name in * do action statements done

20. Review Command Structure • while [ condition] do action statement(s) done • if [ condition ] then action statement(s) fi

21. Review Command Structure • for name in * do action statements done Example: while [ "$1" != "" ] do $size = 0 done

22. Review Command Structure Examples: if [ $# –ne 1 ] then echo “Please enter a command line argument” fi logfile="/var/adm/messages" foreach mon in Sun Mon Tue Wed Thu Fri Sat do grep $mon $logfile > $logfile.$mon end

23. Next Weeks Lab Assignment • Review Lab Assignment 2-1 Simple Shell scripting. • Lab assignments should be recorded on cs.franklin.edu (Einstein) machine in your “~/itec400/homework” directory. • Demonstrate how to create a file using the “vi” editor. • Execute printnum.sh and maxlines.sh scripts on the cs.franklin.edu machine. • Lab Assignment 2-1 will be complemented with script logic. Script logic will be utilized to jump start the lab assignment. It contains script logic, 70% percent of the needed coding, and helpful hints to assist your programming skills. In addition to script logic, you will receive a Shell and Perl Commands Quick Reference document in email.

24. Break Out Problems • Program statement (#!/bin/ksh) • less • ps –ef | wc –l • who | awk ‘{print $1}’ | sort –u | wc –l • ps –ef | awk ‘{print $1}’ |sort –u | wc –l • find / ex • ps –ef | awk ‘{print $9, $1}’ • Shell language syntax: $# • Shell language command: for name in * • Shell language command: NUMBER=$(($NUMBER - 1)) 11. Shell variable:PATH

25. Upcoming Deadlines • Lab Assignment 1-1, Obtain a Proctor for Exams, due May 6, 2012. • Lab Assignment 1-2, Install VMware and Knoppix Virtual Machine, due April 29, 2012 • Lab Assignment 1-3, Introduction to Linux, due April 29, 2012 • Lab Assignment 2-1, Simple Shell Scripting, due May 13, 2012 • Lab Assignment 3-1, Advanced Scripting, due May 20, 2012. • Read Chapters 1 and 2 in your text book, Essential System Administration. • Read Module One listed under the course Web site
