- 1absolute pathA path that refers to a particular location in a file system.
Absolute paths are usually written with respect to the file system’s root directory, and begin with either “/” (on Unix) or “\” (on Microsoft Windows). An example of an absolute path is /home/appacademy/Downloads which would be the path for the directory that contains downloads for the "appacademy" account. - 2command-line interfaceA user interface based on typing
commands that interacts with files and the operating system.
On Windows, you will use the Ubuntu environment for that. On macOS, you will use Terminal. - 3current working directoryThe directory that relative paths are calculated from; equivalently, the place where files referenced by name only are searched for.
The current working directory is usually referred to using the shorthand notation "." (pronounced “dot”). - 4file systemA set of files and directories. A file system may be spread across many physical devices, or many file systems may be stored on a single physical device; the operating system manages access.
- 5filename extensionThe portion of a file’s name that comes after the final “.” character. By convention this identifies the file’s type: .txt means “text" file, .png means “Portable Network Graphics" file, and so on. These conventions are not enforced by most operating systems: it is perfectly possible (but confusing!) to name an MP3 sound file "homepage.html" which makes it look like an HTML file for showing content in a Web browser!
- 6home directoryThe default directory associated with an account on a computer system. By convention for your account, all of your files are stored in or below your home directory. On macOS, that is found in the /Users/«your-name»k directory. On Ubuntu, you can find your home directory under /home/«your-name». On Windows, you will find it under C:\Users\«your-name». On Ubuntu and macOS, the shortcut for your home directory is "~".
- 7operating systemSoftware that manages interactions between users, hardware, and software processes. Common examples are Linux, macOS, and Windows.
- 8parent directoryThe directory that “contains” the one in question. Every directory in a file system except the root directory has a parent. A directory’s parent is usually referred to using the shorthand notation ".." (pronounced “dot dot”).
- 9pathA unique description that specifies the location of a file or directory within a file system. There are two kinds of paths: absolute paths and relative paths.
- 10relative pathA path that specifies the location of a file or directory with respect to the current working directory. Any path that does not begin with a path separator character, "/" on Ubuntu and macOS, is a relative path. The path "Documents/Contracts/" is a relative path from the current working directory into a "Contracts" subdirectory under a "Documents" subdirectory. You know that "Contracts" is a subdirectory because there's another path separator ("/") after it.
- 11root directoryThe top-most directory in a file system. On macOS and Ubuntu, its name is "/".
- 12shellA command-line interface such as Bash or Z shell that allows you to interact with the operating system.
- 13subdirectoryA directory contained within another directory. All directories except the root directory are subdirectories.
- 14wildcardA character used to specify a pattern to match. In Bash or Z shell, the wildcard character "*" matches zero or more characters. This means that "*.txt" would match any name that ends with ".txt".
