Using the `/proc` File System and Commands

You can display detailed information about the processes that are listed in the /proc directory by using process commands. The following table lists the /proc process commands. The /proc directory is also known as the process file system (PROCFS). Images of active processes are stored here by their process ID number.

Table 12–3 Process Commands (/proc)

`pfiles`	Reports `fstat` and `fcntl` information for open files in a process
`pflags`	Prints `/proc` tracing flags, pending signals and held signals, and other status information
`pldd`	Lists the dynamic libraries that are linked into a process
`pmap`	Prints the address space map of each process
`psig`	Lists the signal actions and handlers of each process
`prun`	Starts each process
`pstack`	Prints a hex+symbolic stack trace for each lwp in each process
