This isstrace-- a diagnostic, debugging and instructional userspace utility with a traditional command-line interface for Linux. It is used to monitor and tamper with interactions between processes and the Linux kernel, which include system calls, signal deliveries, and changes of process state. Th...

This option is useful if you want to trace multi-threaded process and therefore require -f, but don't want to trace its (potentially very complex) children. -D --daemonize --daemonize=grandchild Run tracer process as a grandchild, not as the parent of the tracee. This reduces the ...

I dumped the core but the size is too big (over 400MB) and it does not allow to attach it. Is there an option in GDB to perform an automatic analysis of crashed application? It does not crash but hangs. I looked at it using linux top command and the process was not active. Transl...
The strace command can be used to intercept and record the system calls made, and the signals received by a process. This allows examination of the boundary layer between the user and kernel space which can be very useful for identifying why a process is
