Processes

Processes can be investigated through a variety of tools:

1. The files in /proc/$PID/, in particular
   • /proc/$PID/fd/*: the open files of the process
   • /proc/$PID/environ: the process' environment
2. strace allows tracing a process' system calls.
3. ltrace allows tracing a process' library calls.

Both `strace` and `ltrace` slow the target process down **a lot**, which might cause problems.
