Homework Help: Unix Shell script

Posted by Tina on Saturday, February 26, 2011 at 1:47pm.

Shell script

Using "if" statement checks for a file called "student.txt" in the current directory. Removes (deletes) the file if it exist. This file will collect last name, first name, and grade for 5 people.

Use a while loop to get the information (last name, first name, and age) for 5 people. grade should be 0-100. Use three different variable names (fname, lname, and grade) to read the data from the keyboard.

Store the data read from the keyboard in a file called "student.txt". After reading all the data for 5 people, display contents of name.txt file on the monitor.

Below is my attempt

if [ -f name.txt ]; then
# I put something in here and it'll be done if the file exists
fi

person_num=1
while [ $person_num -lt 6 ]; do
# put something here to repeat for each person

-p fname
-s name.txt
-p lname
-s name.txt
-p age
-s name.txt
person_num = $(eval $person_num + 1)
done

if[$person_num ==6]
# read name.txt file
-r name.txt
