Toggle caps in terminal

$ CD Desktop/
bash: CD: command not found

$ cd Desktop/
$

The above is a simple example , which normally happens to all one or the other day , you type some command with caps "ON" and the "command not found" , comes up , you then realise that caps was on and you caps "OFF" , then retype the command.

It may not be a big issue , but its annoying at times.

The possible solution would be :

The first word the user types in the terminal will normally be a command , so by default let the terminal be insensitive to "caps on" , if the user paste / use |<- Tab ->| compilation , then the case sensitivity must remain as per the text.
