The Funtoo Linux project has transitioned to "Hobby Mode" and this wiki is now read-only.

Daniel Robbins has developed a custom MediaWiki extension called ConsoleOutput to realistically display console output on the wiki. Here's an example to give you an idea of what it can look like:
root # bluetoothctl [NEW] Controller 00:02:72:C9:62:65 antec [default] [bluetooth]# power on Changing power on succeeded [bluetooth]# agent on Agent registered [bluetooth]# scan on Discovery started [bluetooth]# devices Device 00:1F:20:3D:1E:75 Logitech K760 [bluetooth]# pair 00:1F:20:3D:1E:75 Attempting to pair with 00:1F:20:3D:1E:75 [CHG] Device 00:1F:20:3D:1E:75 Connected: yes [agent] Passkey: 454358 [agent] Passkey: 454358 [agent] Passkey: 454358 [agent] Passkey: 454358 [agent] Passkey: 454358 [agent] Passkey: 454358 [agent] Passkey: 454358 [CHG] Device 00:1F:20:3D:1E:75 Paired: yes Pairing successful [CHG] Device 00:1F:20:3D:1E:75 Connected: no [bluetooth]# connect 00:1F:20:3D:1E:75 Attempting to connect to 00:1F:20:3D:1E:75 [CHG] Device 00:1F:20:3D:1E:75 Connected: yes Connection successful [bluetooth]# quit [DEL] Controller 00:02:72:C9:62:65 antec [default] root #
As you can see, this renders in a way that provides a more realistic representation of what actually happened on a terminal console. The text highlighted in bright white is supposed to be the text that the user has typed in directly.
Console Usage
To display console output, use the {{console}} template:
For a root console:
{{console|body=
###i## run a command as root
}}
Produces:
root # run a command as root
For a non-root console:
{{console|body=
$ ##i##run a command as user
}}
Produces:
user $ run a command as user
To specify a hostname in a prompt, do this:
{{console|body=
%my-hostname% ##i##run a command on a host
}}
Produces:
my-hostname # run a command on a host
Note that we use a # prompt for root, a $ prompt to denote a non-root user and % for a host name. If you need to disable the auto-expansion of an initial #, % or $ to a prompt, start the line with a \ (backslash) character.
{{console|body=
###i## cat > /usr/bin/helloworld.sh << "EOF"
\#!/bin/bash
\# Simple script comment
echo hello world
EOF
}}
Produces:
root # cat > /usr/bin/helloworld.sh << "EOF" #!/bin/bash # Simple script comment echo hello world EOF
The ##i## text tags the rest of the line as being user input ("i" is for "input"). It is then highlighted in a noticeable color so it stands out from text that is not typed in by the user.
If you need to end highlighting of user input prior to the end of a line, use ##!i## to mark the end of the highlighted area.
The following special character sequences are also available:
##g##- Green##y##- Yellow##bl##- Blue##r##- Red##b##- Bold
Please use the above coloring options sparingly. It is sometimes nice to use them to get wiki console output to match the colors that are displayed on a Linux console. Also note that for every color above, there is a matching ##!(colorcode)## option to turn color off prior to end of line.
