Flags

-a	Displays entries in the process table.
-A	Displays all entries in the kernel thread table.
-f	Displays the file table.
-i	Displays the i-node table and the i-node data block addresses.
-p	Displays the process table.
-P	Displays runnable kernel thread table entries only.
-s	Displays information about the swap or paging space usage.
-S	Displays the status of the processors.
-t	Displays the tty structures.
-u ProcSlot	Displays the user structure of the process in the designated slot of the process table. An error message is generated if you attempt to display a swapped out process.

-U ThreadSlot	Displays the user structure of the kernel thread in the designated slot of the kernel thread table. An error message is generated if you attempt to display a swapped out kernel thread.

Examples

To display the i-nodes of the system dump saved in the dumpfile core file, enter:
```
pstat -i dumpfile
```
Symbols are retrieved from the /usr/lib/boot/unix file.
To display the file table and the user structure for the process in process table slot 0 (zero) of the system currently running, enter:
```
pstat -f -u 0
```
To display the tty structures for a system dump, whose core file is dumpfile and whose kernel is the /usr/lib/boot/unix.back file, enter:
```
pstat -t /usr/lib/boot/unix.back dumpfile
```
To display all threads in the kernel thread table and the user structure of the thread in thread table slot 2, enter:
```
pstat -A -U 2
