You do not say what operating system is installed on those two computers. If you use Windows, you can go to the window's header and right-click on it and select Properties. It should be under the Font tab. Finally, when you click on OK, it will ask you if you want to make these changes for this window only or if you want these settings to apply every time for all shell windows.
I like to use the bold large text too, so I changed the font size so that the shell window fills up the whole screen.
If your question is about configuring the syntax highlighting within your text editor so that shell commands (the text within ``) would display in bold, then again, we would need to know which text editor you're using. You didn't mention it. I use Notepad2 in which I Just go to View menu >> Custom Schemes >> Perl Script >> Backticks. And then I enter this: "fore:#FFFFFF; bold;" without the quotes which makes the text appear in bold white letters.
Edit: I just read the comments, and I noticed that you're asking about a Linux system. Sorry. Just ignore my comment. How do I delete what I wrote here? There's an Edit option, but there's no Delete.
