CSC3320 System Level Programming Lab Assignment 4 - Part 2 (Post-Lab) Purpose: Practices on the grep. fgrep. egrep, sed, awk, and sort commands for text processing. Note: Please follow the instructions below, and write a report by answering the questions and upload the report (named as Lab4_P2_FirstNameLastName.pdf or doc) to the folder "Lab4_P2" of the Dropbox in the iCollege system. Please add the lab assignment NUMBER and your NAME at the top of your file sheet. The following table is from Wikipedia. It shows the eleven highest mountains in Georgia.

Open your terminal and connect to snowball server. After that, go to directory Lab4 (cd -Lab4) and please download the file " mountainList.txt" by the following command (internet access required): /home/yye10/public/mountainList.txt mountainlist.txt Be sure it succeeds using ls to see the file name "mountainList.txt listed. cp 8) Use sed to delete the lines where the mountains are only at Union County in "mountainList.txt".
