You can use the command-line environment interactively by typing a command and waiting for a result, or you can use the shell to compose scripts that run without direct interaction.
Execute commands in the shell
In the Terminal app on your Mac, enter the complete pathname of the tool's executable file, followed by any needed arguments, then press Return.
If a command is located in one of the shell's known folders, you can omit path information when entering the command name. The list of known folders is stored in the shell's PATH environment variable and includes the folders containing most command-line tools.
For example, to run the ls
command in the current user's home folder, enter the following at the command prompt, then press Return:
To run a command in the current user's home folder, precede it with the folder specifier. For example, to run MyCommandLineProg
, use the following:
% ~/MyCommandLineProg
To open an app, use the open command: Jailbreak ipod touch 5.
When entering commands, if you get the message command not found
, check your spelling. Here's an example:
Mac Bash Commands
% opne -a TextEdit.app
zsh: opne: command not found
Terminate commands
In the Terminal app on your Mac, click the Terminal window that is running the command you want to terminate.
Press Control-C.
This sends a signal that causes most commands to terminate.
Repeat previously entered commands
The commands you enter during a session are saved so you can repeat a previously used command without retyping it.
In the Terminal app on your Mac, press the Up Arrow key.
The last command you entered appears on the command line.
Continue pressing the Up Arrow key until you see the command you want, then press Return.

Terminal User Guide
Instead of entering commands and waiting for a response, you can compose shell scripts that run without direct interaction.
A shell script is a text file that contains one or more UNIX commands. You run a shell script to perform commands you might otherwise enter at the command line.
Shell scripts are useful because you can combine many common tasks into one script, saving you time and possible errors when performing similar tasks over and over. You can also automate shell scripts using tools such as launchd
or Apple Remote Desktop.
A shell script begins with a character combination that identifies it as a shell script—specifically the characters # and ! (together called a shebang) followed by a reference to the shell the script should be run with. For example, here's the first line of a shell script that would be run with sh
:
You should document your shell scripts with comments. To add a comment, start the line with the number sign (#). Every line of a comment needs to begin with the number sign:
#This program returns the
#contents of my Home folder
Mac Terminal Commands Cheat Sheet
You can put blank lines in a shell script to help visually distinguish different sections of the script.

You use the chmod
tool to indicate that the text file is executable (that is, its contents can run as a program). See Make a file executable in Terminal on Mac.
