Specify the name of the directory (folder) you want to create just after it. If I wanted to create a folder called new-folder, I would run: mkdir new-folderLet's look at concrete examples. Creating folders Non-code exampleScenario: You're at university, and you've just started your second semester.

Substitute another folder name from the list outputted by the ls command). Cd DesktopMake a directory (folder) called School: mkdir SchoolChange directories into the School directory: cd SchoolYour Terminal window will look like this: Make a 'School' directory (mkdir School) and move into it (cd School)Simply making a folder using mkdir doesn't move you into that folder.

We've just created a folder called 'School' in order to stay organized. In theory, I'd run mkdir Second semester to create a folder inside called 'Second semester,' right?Nope! 😖 You need to make special considerations for folder names that contain spaces.Notice that, by running mkdir Second semester, two folders (1. 'Semester') are created instead of one: mkdir mistakes: two folders instead of oneBy running mkdir Second semester, I've accidentally created 2 files: one called 'Second' and one called 'semester.' This is because my computer interprets the space between the two words as a delineation between two folders names, not just a space in the middle of one name.Clearly, we need a different way to indicate 'Second semester' is all one file name; not two separate ones. Multi-word folder solutionsTo create or reference a folder with multiple words in it, you have three options:.use quotation marks, i.e., mkdir 'Second semester'.This says the folder name should include all characters inside the quotation marks.escape the special character (the character you're computer is interpreting in a special way) using a backslash, i.e, mkdir Second semester.This says that the special meaning of the space between 'Second' and 'semester' should be ignored.
A directory is a container that is used to contain folders and file. It organizes files and folders into a hierarchical manner.There are several logical structures of a directory, these are given below. Single-level directory –Single level directory is simplest directory structure.In it all files are contained in same directory which make it easy to support and understand.A single level directory has a significant limitation, however, when the number of files increases or when the system has more than one user. Since all the files are in the same directory, they must have the unique name.
