Assignment Goals: To learn to use UNIX/Linux file processing utilities to process data in text files. Tasks: 1. In your home directory, make a directory called hw3 and change to the hw3 directory. 2. Use the vi editor to create three text file s1, s2, and s3. Each contains a list of full names as follows. Assume a school department offers three scholarships to students. A student can apply for one scholarship or more scholarships. The files s1, s2, and s3 are students who applied for Scholarship 1, Scholarship 2, and Scholarship 3, respectively. The student names are sorted in the alphabetic order Amanda Jones Amber Johnson Brandon Brown Chris Davis Daniel Hall Elizabeth Walker Frank Thompson Jack Moore Kevin Young Nick Turner Noah Parke Robert Wright Tyler Cooper Aaron Smith Amanda Jones Ben Miller Brandon Brown Brian Wilson Daniel Hall Edward Thomas Frank Thompson George Anderson John Martin Loren Adams Noah Parker Peter Hill Steve Jones Wayne Philips Aaron Smith Brandon Brown Chris Davis David Clark Edward Thomas Jack Moore John Martin Kevin Young Michael Harris Nick Turner Peter Hill Robert Wright 3. Use the vi editor to create a script called hw3script and add commands as follows: 3.1. Write commands to find and display the number of students who applied for each scholarship. 3.2. Write commands to find and display students who applied for two scholarships, Scholarship 1 and 2, Scholarship 1 and 3, or Scholarship 2 and 3, respectively 3.3. Write commands to find and display students who applied for all three scholarships. Hints: Store results of 3.2 in intermediate files and use them in step 3.3 3.4. Write commands to find a complete list of students who applied for scholarship(s) and output the result to a file named applicants. The result should NOT contain duplicates. Hints: Merge student names in a proper way and remove the duplicates. 3.5. Use a command to replace "Ben" with "Benjamin" in the applicants file and save the output to a new file applicants final 3.6. Use a command to find all the lines that contain the name "Jones" in the applicants final file 3.7. Write a command to display the final list of students who applied for scholarship(s). 3.8.
