Link of the week Knoppix is an open source software that is based on Debian. A live-Linux CD means that the computer boots and executes solely from the CD. The CD does not install software instructions or data on your hardware drive keeping it ready for reuse. Knoppix includes the open source packages: Linux software Desktop environments (OpenOffice.org, Konqueror, Firefox, Apache, PHP, MySQL)

Use of the Virtual Machine Caveat: Knoppix software was designed to be used as a Live CD because of specific features that make it’s performance and stability very suitable. It has been noted in several articles that Knoppix works best from a Live CD. Knoppix enthusiasts have attempted to install this software on a hard disk and encountered problems in the process. These problems are most pronounced when installing updates and new software.

Review week two lab assignment The Advanced Scripting lab assignment requires two shell scripts to be written. - srch.sh - srchfile.sh The srch.sh script will call the srchfile.sh script to perform a specific task. That specific task is task to search a file for a pattern and report it to standard output. When the end of file is reached, control is then returned to the main script (srch.sh). Shell syntax srchfile.sh $1 $2 original=$PWD cd $original cd $2 listing=`ls –l | cut –f9` for file_name in listing do … done

Review week two lab assignment

ls –l | more ls –l | less (count the fields/use “q” to quit) ls -a (does not hide entries) less man (utilizes the less command for reading online documentation). cat > test_file (keyboard input goes into test_file) cat < test_file (test_file is displayed on terminal) cat foobar_2 >> foobar_1 (append first file to second file) who | sort > test_file.txt The output of the who command is piped to the sort function and written in ascending order in the test_file.txt file.

Review week two lab assignment > test_file cat /etc/passwd grep x /etc/passwd | cut –d’:’ –f1 chmod 705 * chmod 705 test_file grep lines ~dandrear/Fall_solutions/foobar_1 find ~dandrear –type d -print myArray[1]=$1 $0 Demonstrate the.profile settings umask 077 (specifies what permissions the system should remove)

Review week two lab assignment HOME = is set to the full path name of your login directory (/export/home/dandrear) PATH = contains the command search path. It is set to a series of path names separated by colons (:). SHELL = This entry may be set by the system administrator to the path name of a shell interpreter other than the standard bash. TERM = specifies what terminal you are using. TMOUT = variable contains the integer attribute. If you set the value greater than zero, ksh terminates if you do not enter a command within the prescribed number of seconds after ksh issues the PS1 prompt. MAIL = Name of your Mail files EDITOR = Pathname for your editor

Week’s 2 & 3 expected outcomes Upon successful completion of this module, the student will be able to: Create scripts using shell/Perl variables and program control flow. Use redirection and pipes to combine scripts and executables. Use man page system and find script tools. Discuss Perl Language

Next lab assignment Introduction to Perl Perl - Practical Extraction and Report Language Perl is a simple language - Compiles and executes like a shell script or a batch file - Perl doesn’t impose special growth limitations on arrays and data strings - Perl is a composite of C, AWK, and Basic - Originally developed to manipulate text

Next lab assignment Perl’s range of flexibility - System administration - Web development - Network programming - GUI development Major features - Procedural Programming Sequence or unstructured statements Includes routines, subroutines, methods, or functions - Object Oriented Programming Module uses “objects” and their interactions to design applications and computer programs.

Next lab assignment Major features (continued) - Powerful built-in support for text processing - Large collection of third-party modules.

Next lab assignment Perl text book read in Chapter one (1), pages 6-14 Chapter two (2), pages 52-56, Chapter three (3), pages 86-88, Chapter thirty two (32), pages 865, 899 Chapter thirty three (33) provides diagnostic messages for output errors.
