strace
System call tracer
strace is a system call tracer, i.e. a debugging tool which prints out
a trace of all the system calls made by another process/program.
The program to be traced need not be recompiled for this, so you can
use it on binaries for which you don't have source.

iotop-c does for I/O usage what top(1) does for CPU usage. It watches I/O
usage information output by the Linux kernel and displays a table of
