GSTACK(1)                  Linux Programmer's Manual                 GSTACK(1)


NAME
       gstack - print a stack trace of a running process


SYNOPSIS
       gstack pid


DESCRIPTION
       gstack  attaches  to  the active process named by the pid on the command line, and prints out an execution stack
       trace.  If ELF symbols exist in the binary (usually the case  unless  you  have  run  strip(1)),  then  symbolic
       addresses are printed as well.


       If  the  process  is part of a thread group, then gstack will print out a stack trace for each of the threads in
       the group.


SEE ALSO

       nm(1), ptrace(2), gdb(1)
