Styling 'inxi' to suit your Destop Manager's colour theme

Tips, Tricks and Tutorials Tips & Tricks
1

If you are like me, you are annoyed by the fact that the report generated by "inxi" highlights the "Category" labels, but de-emphasizes the meaningful data generated for each of those.

The below script changes that for three presets:

  • UbuntuMATE (greenish)
  • Ubuntu (orangy)
  • KDE (blueish)

The code logic can be easily modified (in the script included at the bottom) to apply whichever is your preferred colour scheme, once that is identified.

Here is a sample generated for my system, using the command

USER__inxi_ReportColourized.sh --ubuntuMateSpecs

SNAPSHOT__System_OasisMega1
SNAPSHOT__System_OasisMega1804×764 111 KB

Adding "--ubuntu" to above command line:

SNAPSHOT__inxi__ubuntu
SNAPSHOT__inxi__ubuntu799×766 115 KB

Using "--kde" instead of "--ubuntu":

SNAPSHOT__inxi__kde
SNAPSHOT__inxi__kde796×761 116 KB

Script (USER__inxi_ReportColourized.sh):

#!/bin/bash

Works pretty good :slight_smile:

But what about the difference between the real accepted options and the options that the "error message" pretends to be valid ?
(see this "broken down" piece of the case statement)

"--ubuntuMateSpecs" ) ;;
"--hide" );;
"--mate" );;
"--shortlist" );;
"--themes" );;
"--ubuntu" );;
"--kde" );;
* ) printf "\t Invalid parameter used on command line. Only valid options:
[ --default | --shortlist {cases} | --samples ] \n Bye!\n\n" ; exit 1 ;;
