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=">> "
export PS1=">> "
sets the command prompt variable and exports the variable. Here we change the default command prompt from$
to>>
.- After using the
source
command, 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.
