Ctrl+spacebar works for both Windows and Linux platforms.
Answer from jeevan on Stack OverflowIn Linux, any special character can be literally inserted on the terminal by pressing Ctrl+v followed by the actual symbol. null is usually ^@ where ^ stands for Ctrl and @ for whatever combination on your keyboard layout that produces @.
So on my keyboard I do: Ctrl+v followed by Ctrl+Shift+@ and I get a ^@ symbol with a distinguished background color. This means it's a special character and not just ^ and @ typed in.
Edit: Several years later and a few input variations implemented by different terminals using keyboard layouts that require pressing Shift to access @.
- Ctrl+v followed by Ctrl+Shift+@
- Ctrl+v followed by Shift+@ without releasing Ctrl.
- Ctrl+Shift+v followed by @ without releasing Ctrl+Shift.
- Ctrl+Shift release Shift and re-press Shift keeping both Ctrl+Shift pressed followed by v and finally @. Seen in some terminals that implement a special input on Ctrl+Shift.
$ echo -e "this is a sentence \0 test123"
this is a sentence test123
The null here ^^ IS NOT visible
$ echo -e "this is a sentence \0 test123" | cat --show-nonprinting
this is a sentence ^@ test123
But it IS here ^^
But maybe you did not want this for a script?
This is not possible to do with Notepad, however, it can be done with a more advanced editor.
With Notepad++
Go to
Edit > Character Panelto show the ASCII Insertion Panel.Put the cursor where you want to insert the character.
Double-click the character (in the Character column) to insert.
With Notepad++
From HEX
- Type 00 00 00
- Select this text
- TextFX > TextFX Convert > Convert Hex to text
From Base64
- Type AA==
- Select this text
- Plugins > MIME Tools > Base64 Decode
The mapping is:
NUL -> AA=
NUL NUL -> AAA=
NUL NUL NUL -> AAAA
I received a couple of error messages from graylog, which complained about the backend could not handle a null character in the form of '\u000', I tried providing '\u000' from my keyboard as the null character,but could not trigger this error.
Does anyone know how I can provide a null character from my keyboard so that I can manually trigger this error?
