Raspbian for example, has a default user "pi" with a default password of "raspberry". Plus ssh server installed and enabled by default. And a very exposed sudoers configuration. Plus no default firewall. It's more common than you would think.

Well sure, embedded systems almost always have default accounts, since the OS is pre-installed and you just boot it up. It's understood that the first thing you do with these systems is change the password, especially if it's going to be exposed in any way to the outside world.

I thought you were talking about normal distros that get installed on general purpose machines.

What's a "Window Keyboard shortcut list"?

That works with CTRL-t, I think CTRL-Enter can't be distinguished from Enter unless you do something special to your terminal. The above should work with any system using bash.

Thus is exactly what I wanted, thanks.

On my Ubuntu I needed to create a new .inputrc.

Code:

cat .inputrc
$include /etc/inputrc
"\C-t": "echo Yes\n"
"\C-x\C-r": re-read-init-file
"\C-e": "\C-p\C-asudo "

line 1 includes the system default file.
line 2 is a test just to see if my file was loaded.
line 3 enables reloading my file. This should be default but it is not.
line 4 uses CTRL and e too recall last line and pre-pend sudo.

I could not figure out how to configure CTRL and Enter?
Also I could use the command format to display the key-binding for a terminal window. All my googling have filed me.

Thanks for your time.

There are several ways to modify your keyboard input commands.

Bash readline
Main->Settings->Keyboard->application shortcuts
Xorg ketboard shortcuts

It all depends on what you need and want you know or are willing to learn.
The people on this forum are very sharp and willing to help you if you ask the right question. Again, it all depends on what you want to do. In my last post, I showed one method that worked for me.

Google is your friend.

Depends on the terminal emulator. Generally, Enter sends a CR character which is encoded as Ctrl+M, so Ctrl+Enter would be Ctrl+Ctrl+M which is nonsensical (hence each terminal make some "sensible" decision about what to do in this case).

Was that a question?

Indeed, and I couldn't tell which you meant.

Yes, that was a question, how can I display/show the BASH keyboard binding?

You can use the dump-functions and dump-macros functions (you'll have to bind them to something).

dump-marcos() fails!
typeset -f works.

The command I needed to use is "bind -s" for user defines.

Thanks.

What you want to know you will find within

/usr/share/X11/xkb/symbols.

I use the ca keyboard layout so,

less ca

shows me the bindings.

For example,

less us

shows me the US keyboard bindings.

(I added EuroSign and yen to both the us and ca keyboard layouts and on logout/login, the new bindings are present

You may also want to look at wikipaedia for what is a pc104 and what is a pc105 keyboard layout.
