by a colon (:) character. Use the -h option to print the usage menu.
The following exit values are returned:

-lPrint the start and end addresses of text and data segment mappings for the shared libraries
The –l option can be used to print the start and end address of text and data segment mappings
of each shared library used by the process.

Printing a Stack Trace with pstack(1)
Given the PID of a running process or the full path to a corefile, the pstack command prints the
stack trace for each lwp thread in the process. To obtain symbol information, pstack searches load
modules (executable/shared libraries) in the current directory, $PATH, $LD_LIBRARY_PATH, and
$SHLIB_PATH. The executable path can be specified along with the PID/core-file-path, separated
by a colon (:) character. If a load module is not found, symbol information for frames in that module
is not displayed.
The pstack command works by attaching to the running process and reading its registers, memory,
and stack. Mismatch between executable and corefile may result in unpredictable behavior.
The following exit values are returned:
0:Successful operation
non-zero: An error has occurred.
