NAME
gstack - Print a stack trace of a running program
SYNOPSIS
gstack [-h | --help] [-v | --version]
pid
DESCRIPTION
Print a stack trace of a running program with process
ID pid. If the process
is mult-threaded,
gstack outputs backtraces for every thread which exists
in the process.
The script invokes GDB, attaches to the given process ID, prints the stack trace,
and detaches from the process.
gstack exits with no-zero status if "gdb" was unable to attach to
the given process ID for any reason, such as a no-existent process ID or
insufficient privileges to attach to the process.
