Please Note: In this exercise, we will work on .bash_profile in the starting directory, not the home directory. This exercise’s starting directory is ps1-variable.
PS1 is an environment variable that defines the makeup and style of the command prompt.
What happens when this is stored in .bash_profile?
export PS1=">> "sets the command prompt variable and exports the variable. Here we change the default command prompt from$to>>.- After using the
sourcecommand, the command line displays the new command prompt.
Let’s try it out!
Instructions
Open .bash_profile in nano.
On a new line, beneath the last entry, set the PS1 variable equal to ">> " (make sure there is one space following >>).
Save the file and exit nano, and click the Check Work button.
Use source to make the changes in .bash_profile available. The command prompt should now look like >>.
Hit Enter with or without typing in commands to see that the prompt is now changed to >>. Click the Check Work button when done.
