How to add custom icons to our bash?

So edit your .bash_profile with your favourite editor vim, nano for example, and add the line:

Open Emoji & Symbol panel and drag and drop your favorite emoji inside quotation marks.

Grag Emoji
Drag emoji inside quotation marks

Depending on terminal settings, nothing may be visible after using drag & drop. Close and reopen you terminal and voilà:

\d Current date
\t Current time
\h Host name
\# Command number
\u User name
\W Current working directory (ie: Desktop/)
\w Current working directory with full path

This is my favourite customisation:

Fontawesome icons inside a palaceholder

This is one way to use fontawesome icons inside a palaceholder:

in the CSS you have to use this code for the class fontAwesome:

After that in the HTML you have to add the **fontawesome class** first and then the **fontawesome icon code** inside the placeholder:

and it’s done!!!

You can simply apply the class every time inside your input with the relative code in the placeholder.

And even more, you can use this method by entering the code into a generic element such as a link or a simple text using the same class “fontAwesome” used for the placeholder:

You can see the result or read the post from my codePen post.

font file for download.

You place the @font-face directive in your style sheet, just like a regular style.

For example, say you’re using the League Gothic font. You have a True Type file named League_Gothic-webfont.ttf inside a fonts folder on your site.

You’d instruct a browser to download this font by adding the @font-face directive to your style sheet like this:

The first property, font-family, you’ve seen before (page 127), but here it has a different purpose. When used inside an @font-face directive, font-family assigns a
