Does the existence of Ctrl+L speak against the existence of the "clear" 
command? So, moot point.

This has nothing to do with Ctrl+L. This is not a debate about Ctrl+L 
versus "clear".

He already did that. He is asking for a default.

How on earth can you assume he didn't add it himself?

Not everyone uses every command that exists in Linux, that is not an 
argument for removing all the commands not everyone uses.

So, moot point.

If you want to suggest Ctrl-L again that's fine, but this is not a 
discussion of Ctrl+L versus a command.

The 'dir' command also exists. I do not use it but I use 'vdir' 
extensively.

This isn't about learning a new language.

The point is that many people use both languages at different times. 
Having a common "verb" can help with muscle-memory-operations because 
switching from one shell to another you keep typing either one.

So for instance if you come from a Windows desktop and you work on a 
Linux server you will be tempted to constantly use "cls", or, if you are 
like me working more in a Unix shell, you are tempted to constantly use 
"clear".

Yes it is. And Debian as well.

So you make it about Ctrl+L again.

I am sorry but your particular preference for a shortcut over a command 
has very little to do with adding an alias for the command.

I just meant to say here that while I'm not particularly for the idea, I 
think your arguments are rather bad.

Personally I do agree with your language argument in the sense of not 
watering down Linux in favour of Windows because:

- I do not like all the short commands
- Clear is a clearer word than cls
- In this case it would be better if Windows moved towards Linux
- I would not hold the same opinion when it comes to something like 
"move" vs "mv" or "copy" vs "cp" which I think would be very nice if it 
became Linux jargon.

So sorry for this lengthy message, I back your position Ralf, but only 
in this particular case because I think the Linux command is better and 
you shouldn't invite people to use the lesser variant.

So for me it is just based on individual merit.

So I think there is an actual argument against this particular case, 
that's all.

Regards.
