The URLs of the form `help://man/<section>/<page>` link to another help page inside the help application. All previous relative page links are replaced by this new form. This doesn't change any behavior but it looks much nicer :^) Note that man doesn't handle these new links, but the previous relative links didn't work either.

## 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)](help://man/1/watch) to emit a backtrace of pid 124, every second:
|
|
|
|
```sh
|
|
$ watch -n 1 -- bt 124
|
|
```
