Tracing what a Linux process is doing

From time to time you will get hanged process or you are unsure of what a process is doing at that moment.

You can trace what a process is doing by running:

# strace -p PID

Where PID is the process ID. Whis will show you what that process is doing in real time.

This is usefull for detecting  exploits or the source of a hang process.

To detach from that process simply press CTRL + C.
