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 • $# - 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.

17. 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 Slash 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`

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

19. Review shell syntax • while [ condition] do action statement done

20.

21. Break Out Problems • Program statement (#!/bin/ksh) • less • ps –e | 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
