pwatch is a set of tools for analyzing what a process is doing. Only the "io" command is currently implemented. It presents I/O activity in a nice ncurses screen and allows you to sort by the read/write speed or the number of bytes read/written since the start of the program. It was written to easily detect which program is eating a lot of I/O bandwidth. License: GNU General Public License (GPL) Changes: This release added a warning for users without a recent kernel, renamed "iotop" to "io", improved speed of scrolling, uses netlink for getting statistics about processes (instead of /proc/pid/io, which is racy), and made many small fixes.
