Use linux commands

5. Add a single-line sentence to the yourname file in the abc123 folder (you can use either a command or a text editor). 6. File /etc/DIR_COLORS is the configuration file controlling the font colors of the files and directories. Please utilize I/O redirection and pipe commands to redirect and attach the line DIR 01;34 of the DIR_COLORS file to the yourname file. The yourname file should end up with 2 lines. The first line is the sentence created in step 5 and the second line is what was redirected from the DIR_COLORS file (which should be DIR 01;34 #directory). 7. Install Vim by using the package manager (Internet connection is needed). 8. Open file /etc/DIR_COLORS with Vim, search for the line DIR 01;34 #directory, modify 34 to 36, save, and exit Vim. Reboot the OS then check if the font color of directory has been changed to cyan (as Fig. 1 shows).
