The second window or tab will start a second, new bash shell. If you prefer you can also open new shells in a new Tab with ⌘T. It is easier to remember the ⌘N (command-N) keystroke. You can open a second terminal window by selecting ‘New Window with Settings – Basic’ from the ‘New Window’ menu in the ‘Shell’ menu. Terminal on macOS will also display the current working directory in the window title bar. This helps you remember your ‘bearings’ in terminal. You may have noticed that the prompt displays the name of the current directory. You can also navigate to an absolute path: Mac:Documents armin$ cd /Library

The pwd command prints the full path of the working directory.

Use the cd command with a relative path Documents and the shell changes it working directory there. You can change the current working directory with the cd command (change directory): Mac:~ armin$ cd Documents You can ask the shell for the current working directory with the pwd command. It is surprisingly easy to lose track of the current working directory. Full paths are also called ‘absolute’ paths. Full paths start with a / and are based in the file system root. Relative paths do not have a leading / and are relative to the current working directory.

Refers to the file ‘hello.txt.’ in the folder ‘Documents’ in the current working directory. Refers to the file ‘hello.txt’ in the current working directory. When using relative paths, there is no initial /. You can refer to files and folder relative to the shell’s current working directory. To help with that a shell has a ‘current working directory.’ Relative PathsĪddressing files and folders with their full path each and every time would be very tedious. Note: Finder in macOS and other graphical interfaces use the word ‘folder.’ Unix and other command line shells use the word ‘directory.’ They are the same. This path tells me (and the shell) that there is a file ‘hello.txt’ in a folder ‘Documents’ in a folder ‘armin’ in a folder ‘Users’ on the root of the file system, the current startup volume. Note: The file system root / should not be confused with the system user root. On macOS the root of the file system is the top level of the volume or disk with the active system, i.e.
MAC TERMINAL COMMANDS GO BACK DIRECTORY SERIES
The complete series of folders to a file or folder is called its ‘path.’įor example, if there is a file hello.txt in your Documents folder in your home directory, its complete path or absolute path is: /Users/armin/Documents/hello.txtĪ path starts at the ‘root’ of the file system, which is shown as simply /. In a Unix shell you denote a folder or file in another folder with the forward ‘ /’ slash character. Modern file systems are hierarchical and have many folders and files nested in each other. On macOS, Terminal will also show the working directory in the window title bar. Pwd is short for ‘print working directory.’ It shows the folder this shell is currently working in, much like a Finder window displays the contents of a certain folder. Depending on the configuration of your Mac, your path might be entirely different. Unless your name is also armin, the path will end with your user name, not mine. You entered the command pwd and the shell returned a result: $ pwd For example, the pathname My Disk is “My Disk” or My\ Disk.If you like this series and want to learn Terminal and the shell on macOS in more detail, get my book “ macOS Terminal and Shell“ Working Directoryīack to our earlier example, the pwd command. Although some file systems permit the use of these other characters, including spaces, you might need to add single or double quotation marks around pathnames that contain them.įor individual characters, you can also use an escape character-that is, put a backslash character immediately before the character in your string.

Avoid most other characters, including space characters. Most of these users aren’t traditional user accounts with home directories, but you should be able to find the short name of known users on the computer.įile and folder names can include letters, numbers, a period, or the underscore character. In macOS, this folder is in the local /Users folder or on a network server.įor a list of short names on your server, enter dscl. To specify another user’s Document folder, use the short name preceded by the tilde (~) character-for example, ~jsmith/Documents. For example, to specify the Documents folder of the current user, enter ~/Documents. The tilde character represents the home folder of the logged-in user. For example, the string “./Test” represents a sibling folder (named Test) of the current folder. Two periods represent the parent folder of the current folder. For example, the string “./Test.c” represents the Test.c file in the current folder. A single period represents the current folder.
