**problem:** `ctrl`+`U` will not kill my terminal program. 

---

**details:** Here are my results from `ssty --all`: 

```
speed 38400 baud; rows 24; columns 80; line = 0;
intr = ^C; quit = ^\; erase = ^?; kill = ^U; eof = ^D; eol = M-^?; eol2 = M-^?;
swtch = M-^?; start = ^Q; stop = ^S; susp = ^Z; rprnt = ^R; werase = ^W;
lnext = ^V; flush = ^O; min = 1; time = 0;

```

As you can see, it describes the available signal interrupts:  

`^C` = `intr`  

`^ \` = `quit`  

`^U` = `kill`  

etc ...

Here is an infinitely running program: 

```
int main (){while(true){}}

```

`ctrl`+`C` works 

```
$./main                                                             
^C
$

```

`ctrl`+`\` works 

```
$./main                                                           
^\[1]    6331 quit (core dumped)  ./main
$

```

`ctrl`+`U` **does not** work.  

Why can't I kill a terminal program this way? 

I could of course find the process id and run `kill -9 <PID>`,  

but I want the shorthand to work.

I'm on Ubuntu: 

```
lsb_release --all 
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 14.04.5 LTS
Release:    14.04
Codename:   trusty

```

Here are my terminal specs, but I've tried other terminals (probably not relevant)

```
gnome-terminal --version                                           
GNOME Terminal 3.6.2

```

It didn't work on xterm either. I've also tried different shells:  

`sh`, `bash`, ans `zsh`. 

What could the problem be? Where should I look now?
