On Linux systems, files are named in a manner similar to other systems such as

Windows, which of the following are some of the important differences?

Group of answer choices

Filenames and commands in Linux, like Unix, are case sensitive$.$ The filenames $$File$1$ and $$file$1$ refer to different files.

Files in Linux begin with an $\text{'}$f$\text{'},$ while directories begin with a $\text{'}$d$\text{'}.$

Linux has no concept of a $$file extension$$ like some other operating systems. You may name files any way you like.

Though Linux supports long filenames that may contain embedded spaces and punctuation characters, limit the punctuation characters in the names of files you create to period, dash, and underscore. Most importantly, do not embed spaces in filenames. If you want to represent spaces between words in a filename, use underscore characters.

Filenames that begin with a period character are hidden. This only means that ls will not list them unless you say ls $-$a$.$
