The default interactive PS2 value prompt for a multi-line command is “ >“ which indicates that you can continue the command on the second line and so on. It makes the command too long for one line, so it can be broken down into multiple lines by giving “ \” at the end of each line. When we are in the console, we can need to associate many commands in one command. 5: Divide the prompt into multiple lines with \n for long command export 2) Change the bash prompt PS2 If we use another annotation, the shell will consider all after the equal sign as the value and we will not have the result we attend.Įxample 2: We simulate an error while displaying username and hostname because we will use ^ instead of " export PS1=^\u - \h$ ^Įxample 3: Passing string to PS1 variable export PS1=happy-test$Įxample 4: Add time to the prompt with \t and the working directory with \w user01 - server01$ export PS1=" " Note that after the equals sign, we use the double quote ( "") to use the \u and \h values. We can see immediately the change on our console. It will help to switch back to our original prompt easier in case we make a mistake or without having to log out and back in again.Įxample 1: Display only the username and the hostname with the separation character “-”: export PS1="\u - \h$ " We will do some examples but before manipulating the value of theses variables, we need to save the file which contains all. \] This sequence should appear after a sequence of non-printing characters. This allows bash to calculate word wrapping correctly. \[ This sequence should appear before a sequence of characters that don’t move the cursor (like color escape sequences). \xxx Inserts an ASCII character based on three-digit number xxx (replace unused digits with zeros, such as “\007″) \$ If you are not root, inserts a “$” if you are root, you get a “#” \# Command number (this will count up at each prompt, as long as you type something) \! Current command’s position in the history buffer \W The “basename” of the current working directory (such as “koithara”) \w Current working directory (such as “/home/koithara”) \T Time in 12-hour format (such as Time in 12-hour format with am/pm \s The name of the shell executable (such as “bash”) \l The name of the shell’s terminal device (such as “ttyp4″) \j The number of processes you’ve suspended in this shell by hitting ^Z \h First part of hostname (such as “mybox”) \e ASCII escape character (you can also type \033) \a The ASCII bell character (you can also type \007) Look below to have a complete idea for the rest of the prompt: # echo parts that include debian_chroot indicate that if you are operating in a change root environment, the prompt will be modified to remind you. Let’s take a look at the PS1 prompt default value on the terminal There are some other values that we will see later. These are just examples of different values it can take. For the most news Linux systems, the defaults values have which show the username, hostname, the current working directory and the user privilege. PS1 is the default prompt we see every time when we log in the console. Note that in this article, we will use echo command to see the value of the different prompt in our console.
