Periodic Display of Fan Speed with Change Highlights

watch -n 10 -d eval "sensors | grep RPM | sed -e 's/.*: *//;s/ RPM.*//'"
Uses the lm-sensors package in Linux to display fan speed. Grep RPM is used to discover lines containing the text RPM, and sed is used to edit out everything but the RPM number. The watch utility is used to update the display every 10 seconds and -d highlights any changes from the previous value. The eval function of Bash is used to execute the command enclosed in the ".." string.
