Hello as soon as once more for an additional installment of the Linux command-line toys creation calendar. If that is your first go to to the sequence, you is likely to be asking your self what a command-line toy even is? Really, we’re retaining it fairly open-ended: It’s something that is a enjoyable diversion on the terminal, and we’re giving bonus factors for something holiday-themed.

Your Bash immediate presently is likely to be a easy greenback signal ($), or extra probably, it is one thing a bit longer. If you are unsure what makes up your Bash immediate proper now, you could find it in an atmosphere variable known as $PS1. To see it, kind:

echo $PS1

For me, this returns:

[u@h W]$

The u, h, and W are particular characters for username, hostname, and dealing listing. There are others you should use as properly; for assist constructing out your Bash immediate, you should use EzPrompt, an on-line generator of PS1 configurations that features numerous choices together with date and time, Git standing, and extra.

$ PS1='u is chilly: '
jehb is chilly:

To set it completely, add the identical code to your /and so forth/bashrc utilizing your favourite textual content editor.
