Remove the first three lines. Enter line-based visual mode with uppercase V. 7. Remove columns on the first line. Enter visual mode with lowercase v. Lowercase v selects characters on a single line only. The columns after -rw- should be deleted. 8. Remove columns, and the subsequent dot (".") on the remaining lines. Use the visual block mode. Enter visual block with the control sequence Ctrl+V. Use this key sequence to select a block of characters on multiple lines. The columns after -rw- should be deleted. 9. Use visual block mode to remove the fourth column. 10. Use visual block mode to remove the time column, leaving the month and day on all lines. 11. Remove the Desktop and Public rows. Enter visual line mode with uppercase V. 12. Use the :wq command to save and exit the file. Make a backup, using the date (in seconds) to create a unique file name. 13. Append a dashed line to the file. The dashed line should contain at least 12 dashes. 14. Append a directory listing of the Documents directory. List the directory listing on the terminal and send it to the editing_final_lab.txt file with one command line. 15. Confirm that the directory listing is at the bottom of the lab file. 4.
