Link of the WeekOpen Source Software:

• http://en.wikipedia.org/wiki/Open_source• http://freshmeat.net• http://sourceforge.net• Definition of Open Source Software.• List of open source products.• Who benefits from open source products?• What is shared source?

Expected OutcomesUpon 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.

Review Shell syntax• $# - Number of positional parameters• $! - Background PID• $? - Return value• $$ - Process PID• $ - Provides the content of a variable ($NUMBER)• $1, $2, $3 … - The syntax represents the positional

parameters on the command line.• 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.

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`

Review shell syntax• if [ -d "$1" ]• then• fi• wc –l - Word count with –l (line option). Print the new line

counts• ~ - Tilde (~dandrear)
