monitor your CPU core temperatures in real time

while :; do sensors|grep ^Core|while read x; do printf '% .23s\n' "$x"; done; sleep 1 && clear; done;
Watch the temperatures of your CPU cores in real time at the command line. Press CONTROL+C to end. GORY DETAILS: Your computer needs to support sensors (many laptops, for example, do not). You'll need to install the lm-sensors package if it isn't already installed. And it helps to run the `sensors-detect` command to set up your sensor kernel modules first. At the very end of the sensors-detect interactive shell prompt, answer YES to add the new lines to the list of kernel modules loaded at boot.
Sample Output
Core 0:      +52.0?C
Core 1:      +60.0?C
Core 2:      +53.0?C
Core 3:      +52.0?C

What Others Think

Wouldn't watch 'sensors|grep ^Core' be sufficient?

@penpen - thanks for the comment. Indeed, what you mention was the root of my putting this command together. But what I really wanted was the pretty formatting for *each* grep'ed line (which would call for the use of either xargs or a bash loop when xargs falls short of what is needed). Further, you can't feed bash script to "watch" -- it doesn't quite get what to do and it tries to execute script keywords as if they were executables in your $PATH. So yes, there is more than one way to do it, but this canned one-liner gives me the pretty formatting plus the feel of the watch command, where watch would have been the preferred method if it were possible here. And one more thing -- you do need the pretty formatting if you wanted to feed the output to ... konky (for the win!)

What do you think?

Any thoughts on this command? Does it work on your machine? Can you do the same thing with only 14 characters?
