The following is a demonstration of the rwtop program, By default it will refresh the screen every 5 seconds, # rwtop 2005 Jul 24 01:00:43, load: 1.02, app_r: 8 Kb, app_w: 19 Kb UID PID PPID CMD D BYTES 0 20320 20347 bash R 10 0 20320 20347 bash W 95 100 20317 20314 sshd R 650 100 20317 20314 sshd W 733 0 2365 20320 ls W 1300 0 2364 20320 vi R 2323 0 2365 20320 ls R 2485 100 20334 20331 sshd R 3010 100 20334 20331 sshd W 3729 0 2364 20320 vi W 14128 In the above output, we can see that a "vi" process wrote 14 Kb and read 2 Kb. In the following example, we print the top 5 processes in a scrolling output by using "-C" to not clear the screen, # rwtop -C -t5 Sampling...
