Bourne Again Shell (bash), similarly to other UNIX shells utilises environmental variable PS1'' to store prompt string description. Willing to change it, it is enough to replace its value with a new one. The most permanently looking effect can be obtained by performing adequate substitution in start script, which in case of bash is in ~/.bash_profile'' file (~'' stands for the home directory of a user in question).Prompt string can contain sequences like \x'', where x - a character, which during printing of prompt will be interpreted and substituted with specific information, e.g. \t'' - actual time. Description of other standard sequences can be found in man page concerning bash (man bash).Task: Permanently set URL-like prompt of the form:

It seems like you've accidentally cut off the end of your question. However, based on what you've provided, it seems like you're asking how to permanently set a URL-like prompt in the Bourne Again Shell (bash). Here's a step-by-step guide:

1. Open the terminal.

2. Type nano ~/.bash_profile to open your bash profile in a text editor.

3. In the bash profile, you'll see a line that starts with PS1=. This is where the prompt string is defined.

4. Replace the existing value with your desired URL-like prompt. For example, if you want the prompt to look like http://mywebsite.com, you would write PS1='http://mywebsite.com '.

5. Save the file and exit the text editor. In nano, you can do this by pressing Ctrl+X, then Y to confirm that you want to save the changes, and then Enter to confirm the file name.

6. To make the changes take effect, you need to source the bash profile. You can do this by typing source ~/.bash_profile in the terminal.

7. Now, every time you open a new terminal session, your prompt will look like the URL you specified.

Remember, you can use special characters like \t for the current time, \u for the username, and \h for the hostname in your prompt. For example, PS1='\u@\h:\t ' would result in a prompt that looks like username@hostname:currenttime .
