Steps to Configure Terminal Prompt

1. Edit the Bash Configuration File

Begin by opening the .bashrc file in your user home directory. For root users, this would be located at ~/.bashrc:

nano ~/.bashrc

Locate the line that defines the PS1 variable (typically starting with PS1=). To display only the current directory name, modify it as follows:

PS1='\W\$ '

Key components explained:

• \W: Shows only the current directory's base name (e.g., olap-engine)
• \$: Displays $ for regular users or # for root

Alternative option using \w would show the relative path (e.g., ~/EuclidOLAP/olap-engine)

2. Save and Apply Chenges

After making the modificationns, save the file and exit the text editor. In nano, you can do this by pressing Ctrl+O followed by Enter to save, and Ctrl+X to exit.

To apply the changes immediately to your current session, execute:

source ~/.bashrc

3. Verify the New Prompt

Navigate to a directory like /root/EuclidOLAP/olap-engine. Your terminal prompt should now display:

olap-engine#

For regular users, it would appear as:

olap-engine$

4. Additional Customization Options

You can enhance your prompt with additional information using various escape sequences:

• \u: Current username
• \h: Hostname (first part)
• \t: Current time in 24-hour HH:MM:SS format

Example of a customized prompt showing username and current directory:

PS1='\u@\W\$ '

This would produce a prompt like:

root@olap-engine#

By properly configuring the PS1 variable, you can create a more concise and informative terminal experience tailored to your preferences.
