Open my_script with vi using vi my_script.
CREATE AND EDIT TEXT FILE IN TERMINAL HOW TO
We can turn it into an executable program by adding the hashbang, which is a piece of text at the beginning of the script that tells the computer how to execute the program. Our script, my_script is a regular text file. In the exercise above, we invoked the BASH interpreter using the bash command to interpret and thereby execute our short program. These days, however, the distinction becomes blurry as many interpreted languages can compile to fast machine code. We say that compiled languages like Fortran, C, and C++ are low level languages not to demean them, but to indicate that they are closer to machine language. You have already used one of the most popular interpreted langauges, BASH, but are probably also familiar with Python, Perl, R, and BASIC. To execute a text file, we require either an interpreter which carries out the instructions in the text directly, or a compiler, which translates the text into binary which can be then executed by the machine.įor the first portion of the short course, we will deal exclusively with interpreted languages to avoid learning how to compile code. Text files are readable by humans but meaningless to a machine. Files which are encoded in a binary format are not readable by human beings and produce a garbled mess when you try to view them with cat. There are two kinds of files on any computer: binary or text. You could just as easily run the echo command yourself. You are currently inside a BASH shell already (which we call the “login shell”), but you can use the bash program to execute a script inside of a sub-shell. Our BASH script called my_script is one of the shortest scripts you could write. Now that you are back on the command line you can use more or cat to see the file. Type wq, which means “write and quit” in the command prompt and hit enter. While many commands can be executed directly, the command prompt accepts more complicated and useful commands. Open the command prompt with a colon character : which will appear in the lower left.
First, use escape to enter the command mode. Now that we have entered some text, we will use the command mode to save the file and exit. The echo command is actually a program which takes many arguments, all text, and simply repeats them. In the example above we have written a command that echoes some text to the terminal.

Let’s write the echo command shown below.Ī batch script is a text file that holds a series of commands (a “batch”) that you might enter directly into the terminal or shell (N.b. You can always tell when you are in the insert mode because the word - Insert - appears in the bottom of the screen. It is absolutely critical that you understand the difference between these modes. Use the i key to switch to the insert mode and the escape key to return to the command mode. We are currently in the command mode, which is designed for issuing commands and selecting text. The tilde characters ( ~) indicate the absence of text. The bottom right shows the line and character number we have selected. Sometimes there is useful information in the bottom row. It has innumerable advantages over modeless editors which are said to make your fingers gnarled from pressing the control key so much. The ( -y) switch will bypass the confirmation prompt and proceed with installing the package.Note: Vim is a two-mode editor which means that you must carefully pay attention to which mode you are using.
