Explanation:
On October 31, around twelve o'clock at night, the lights were dull. It was Siberian cold and I was walking painfully under the whitish lighting of a lamppost and the retro neon lights of a convenience store in a neighborhood that was buzzing when I went to buy meat. buildings, grayish in this half-light, crumbled under the weight of sleep, while the neighborhood was still open. Its decoration was particularly macabre in tone: synthetic but very sticky spider webs adorned the porches of the terraces, pumpkin ornaments are exhibited like works of art, ... Some pushed the macabre by hanging mannequins made up in corpses. At the entrance to the neighborhood, I found the body of its owner stabbed. Frozen in place, I wondered what else awaits me. My heart was pounding, feeling a shiver of anguish. When I was removing the phone from my pocket to call my police friends, my hands were clenched in fear. An investigation was carried out to find out the causes of death. Also, I went with them so they take my words. Hopefully the murderer will be arrested to put an end to this sybilinous crime.
Answer:
Option 4 is the correct answer to the above question.
Explanation:
In the Linux operating system, The etc folder is listed on the root directory. When any user wants to go in the root directory of the Linux operating system from anywhere, then he needs to follow the command of the name of the folder where he wants to go with the '/' symbols. The above question states that the user wants to go to the etc folder of the root directory, then he needs to press the command '/etc' with the help of cd command because cd command is used to open any folder. So the option 4 is the correct, while the other is not because--
- Option 1 states about cd which gives the error.
- Option 2 states about cd /home/mary/etc which take the user to the etc folder which is in the mary folder.
- Option 3 states about the cd etc which is used to take the user on the etc folder which is in the current folder.
- Option 5 states about the cd\etc which gives the error.
