Terminal User Guide
First of all, you have to start terminal application. You can use either built in Terminal.app, or you can use replacement. My favorite one is iTerm2. Then, you simply open terminal window and run R. Just like shown below: Have fun with R!

Shell scripts must be executable files in order to run. You can use the chmod command to indicate that the text file is executable (that is, its contents can be run as a shell script).
In the Terminal app on your Mac, use the cd command to move into the directory that contains the file you want to make executable. For example:
Enter the chmod command. For example:
% chmod 755 YourScriptName.sh
After making the shell script file executable, you can run it by entering its pathname. For example:
Open App From Terminal Mac
or
% cd ~/Documents/Dev/ % ./YourScriptName.shTerminal User Guide
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:
% ~/MyCommandLineProgTo open an app, use the open command:
When entering commands, if you get the message command not found, check your spelling. Here’s an example:
% opne -a TextEdit.app zsh: opne: command not found
Run Osx App From Terminal
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.
