CSCE 3600: Systems Programming

Recitation Assignment 3 – Sed and Gawk

Due: 06:00 PM on Monday October 12 2020

DESCRIPTION: In this recitation assignment, you will just practice to run sed and gawk commands and record your work session into a file. In other words, just type and run commands specified in bold Consolas (except $ sign :) below on your terminal.

Let’s start. First, open a terminal (bash) session. Issue the first command

$ script FirsName_LastName_04.txt

where FirsName_LastName_04.txt is a file name with FirstName_LastName replaced with your real names. That command will start recording of your work into that file.

The sed commands: go to one of your directories that contains plenty of files (more than 10)

$ cd name-of-directory-with-more-than-10-files

and then in that directory create a list of files by issuing the following command

$ ls –l > sedfile.txt

Print 5 lines of sedfile.txt file to the terminal using statement

$ sed –n 1,5p sedfile.txt

Replace the first “-“character on lines in the file with “R”

$ sed –i "s/^-/R/g" sedfile.txt

-i option instructs sed to replace the original file with output file it creates.

Print 5 lines of sedfile.txt file again to see what was changed

$ sed –n 1,5p sedfile.txt

Delete the first line in the file

$ sed –i 1d sedfile.txt

Find some pattern on one of the lines in the file (like name, date, or memory size) and issue the following command to add new line after that pattern.

$ sed –i '/YOUR PATTERN/a This will be added as new line'

Print out the first 10 lines of your sedfile.txt file again to verify that these changes (deleting the first line and adding a new line) worked:

$ sed –n 1,10p sedfile.txt

Now let’s work with gawk. Create a list of running processes on your system by issuing the following command from your command prompt as follows:

$ ps –ef > gawkfile.txt

Print gawkfile.txt using the NR system variable as follows:

$ gawk 'NR <= 10' gawkfile.txt

This should display the first 10 lines of your gawkfile.txt file. Processes will be covered in detail a little later on in this course. So how many processes are running on your system?

$ gawk 'END {print NR}' gawkfile.txt

Since our gawkfile.txt file contains a header with the fields, we should have 1 less process running on our system. Let’s try to print out only those processes that only you are running. This means that we want to print out some fields where the UID is your user ID. If you do not know your user ID, you can issue the whoami command at your command prompt to find out.

$ gawk '/YOUR USER ID/{print NR, $0}' gawkfile.txt

Let’s see what is result of matching on the first field ($1)?

$ gawk '$1 ~ /YOUR USER ID/{print NR, $0}' gawkfile.txt

That ensures that only the processes that you own are printed!

We see that the first line of gawkfile.txt contains a header with most likely 8 fields (i.e., UID, PID, PPID, C, STIME, TTY, TIME, and CMD, though there might be some variation in different Linux distributions). However, because we use the default field separator of whitespace, some records might contain more fields. So, let’s print out those records that have more than 8 fields. We use here gawk variables NR and NF.

$ gawk 'NF > 8 {print NR, NF}' gawkfile.txt

Now, we print only fields from 9^th to max (NF) on line if line contains more than 8 fields.

$ gawk 'NF>8 {for(i=9; i<=NF; i++) print NR, NF, $i}' gawkfile.txt

Now, we swap the PID (field $2) and PPID (field $3) columns so that each record lists the parents’ process ID first by just printing field in the specified order below (3 before 2).

$ gawk 'BEGIN {OFS="\t"};{print $1,$3,$2,$4,$5,$6,$7,$8}' gawkfile.txt

OFS above is Output Field Separator, so fields in output should be separated by a Tab.

To output result of gawk command to a file instead of terminal you can use redirection

$ gawk 'BEGIN {OFS="\t"};{print $1,$2,$3,$5}' gawkfile.txt > out

Let’s finish your recording session and close your script file

$ exit

You should see now FirsName_LastName_04.txt in the current directory.

REQUIREMENTS: Your typescript file will be graded based largely on whether you completed the work correctly, so you should make sure you obtained meaningful results from each command. • Although this assignment is to be submitted individually (i.e., each student will submit his/her own source code), you may receive assistance from your TA, IA (i.e., Grader), and even other classmates. Please remember that you are ultimately responsible for learning and comprehending this material as the recitation assignments are given in preparation for the minor assignments, which must be completed individually.

SUBMISSION:  You will electronically submit your typescript file FirsName_LastName_04.txt to the Recitation 3 drop box in Canvas by the due date and time. No late recitation assignments will be accepted.

Barnes Company uses a job order cost system. The following data summarize the operations related to production for October:

Airbus sold an aircraft, A400, to Delta Airlines, a U.S. company, and billed $30 million payable in six months. Airbus is concerned with the euro proceeds from international sales and would like to control exchange risk. The current spot exchange rate is $1.05/€ and six-month forward exchange rate is $1.10/€ at the moment. Airbus can buy a six-month put option on U.S. dollars with a strike price of €0.95/$ for a premium of €0.02 per U.S. dollar. Currently, six-month interest rate is 2.5% in the euro zone and 3.0% in the U.S.

1. Compute the guaranteed euro proceeds from the American sale if Airbus decides to hedge using a forward contract.
2. If Airbus decides to hedge using money market instruments, what action does Airbus need to take? What would be the guaranteed euro proceeds from the American sale in this case?      
3. If Airbus decides to hedge using put options on U.S. dollars, what would be the ‘expected’ euro proceeds from the American sale? Assume that Airbus regards the current forward exchange rate as an unbiased predictor of the future spot exchange rate.
4. At what future spot exchange rate do you think Airbus will be indifferent between the option and money market hedge?

Midlife—Making the Most of the “Second Half”

Have you heard the saying, “Life begins at forty?” Unfortunately the cultural messages we receive about midlife are often negative (an emphasis on the development of wrinkles and gray hair, for example) rather than positive (a time of advancement in one’s career, freedom from the responsibilities of caring for young children). Midlife is often a time of transition. People may change careers or end long-term marriages as they assess where they are in life and how they would like to spend the remainder of their lives. Because these transitions are sometimes painful, the concept of the “midlife crisis” has been created and has become popular in American culture. However, there has also been some debate questioning whether the midlife crisis is a universal experience and, in fact, whether it even exists. Review research on the concept of the midlife crisis and draw your own conclusions about its existence and prevalence in American culture. You will also discuss some ways that we can create a more positive image of midlife.

What is the evidence for the existence of the midlife crisis?

Why has the concept become so pervasive in American culture?

Discuss at least two ways that we can create a more positive image of midlife in our culture.
