I taught Linux for entertainment. Linux is the 18 operatng system in my lifetime. I am an old man now at 75. The one thing that gets me upset is using the acrrnym CLI in reference to the Shell you choose in Unix Linux. AIX uses natively the KSH korn shell. Solaris and IRIX use the TCSH shell. Red Hat and most Linux distributions use the BASH or Born SHELL. Why do I get my pantys in a wad. Because the SHELL is a way to talk to the Kernel. Yes you can issue commands to the KERNEL. But you can issue instructions to higher level pprogramming languages through the SHELL. You can issue instructions to the Kernel through the SHELL. Even the GUI uses the SHELL underneath. You can accomplish all Mouse inputs through the SHELL To say the shell is a way of sending commands. Is a limited statement and my OS is only limited to the commands I enter through the keyboard. The fact that you are the least intelligent component of your Kernel. So set aside the Bill Gates term CLI. Your not using that limited Operating System.
Enjoy the blessing Linus Torvalds has given you. There hundreds of thousands of contributors to Linux. All of them have contributed their works to you through the GPL. Meaning you are not required to pay for this pleasure. They will not refuse a gift though. So for the respect of the Linux Community do not pollute Linux with Windows language.
