## Name
bt - view the backtrace of the specified process
## Synopsis
```**sh
$ bt <pid>
```
## Description
This program is used to inspect the current executable state of a process.
It will read the stack of each thread in the process, and symbolicate the
addresses for each frame in the stack producing a backtrace.
**NOTE**:
* Kernel addresses will not be available unless you are super user.
* If Kernel addresses are available, they will not be symbolicated unless
the current user has access to the `/boot/Kernel` file.
## Arguments
* `pid`: Process ID
## Examples
View all stacks of pid number 10:
```sh
$ bt 10
```
Use [`watch`(1)](watch.md) to emit a backtrace of pid 124, every second:
```sh
$ watch -n 1 -- bt 124
```
