Its output contains the process name and the amount of data read or written by the process, in KB. For example: [...] Process KB Read KB Written Xorg 50287 0 staprun 3328 0 multiload-apple 3039 23 sshd 208 1 floaters 14 62 NetworkManager 15 0 gnome-vfs-daemo 8 0 cupsd 3 3 sendmail 4 0 mixer_applet2 3 0 Process KB Read KB Written Xorg 51886 0 staprun 3328 0 multiload-apple 3039 23 sshd 1344 4 snmpd 90 0 floaters 15 66 NetworkManager 23 0 irqbalance 16 0 pam_timestamp_c 9 0 sendmail 4 0 displays top I/O writes and reads within a random 10-second interval.
