Levi can use the bash command to type all the commands on the same line to type one after the other character without requiring input.
<u>Explanation</u>:
- He wants to run five commands. For one command it will take exactly 20 minutes. So it will take one hour forty minutes.
- To type all of the commands on the same line Levi should use the bash command. For inserting the bash command Levi should use backslash \ as the last character of the line.
It really depends on what you're using it for such as looking up a recipe or an answer to a question. If you're using it for illegal purposes or looking up things that are seen as morally wrong by other people it can make the internet seem like a bad thing. But the internet wasn't created with that intended purpose so again it's just your own personal opinion.
Answer:
B. root
Explanation:
Every user in Linux is assigned a folder from which they can store their files. The interpreter allows you to abbreviate your route with the “~” symbol. The ls command without any additional data shows the files in the current directory, but if after the name of the command a path is written, it shows the files in that path. Therefore, the ls ~ command shows the files in the user's folder.
In addition to the folders and files created by the user or programs, every Linux folder has two subfolders defined by default:
“..”: It is the top level folder in the file hierarchy that contains it. This subfolder is also present in the root of the filesystem (the folder with absolute path “/”), but points to itself.
“.”: It is the folder itself that appears as if it were also a subfolder. It can be considered as a "self-reference" or pointer to itself.
These folders are normal folders in the system for all purposes; that is, they can be used on routes. For example, the path /dirA/dirB/dirC/../fichero2.txt refers to the file that is stored in the dirB folder, since from dirC, the folder .. points to its predecessor, dirB. The following figure shows the interpretation of this route as well as the equivalent of the “..” and “.” Folders.
