Why not run the “sensors -f” through sed directly like:

sensors -f | sed -n ’5p’ | cut -c14-16

Thanks.

Have you ever popped the heatsink, cleaned and regreased it, and reinstalled? Has the system always been this way? It sounds like it’s missing the heatsink grease, or just a bad job of installation. If you’ve never done this before, make sure to search for some good instructions. (hint – less is more)

Another example of a stream filter is a filter which takes a file formatted with CRLF end-of-lines as for MSDOS and strips out the CR giving a file which only has the LF (as for Unix) end-of-line.

Why not pipe the output of sensors to sed rather than going to a temp intermediate file?

temperature=(sensors -f | sed -n ’5p’ | cut -c14-16)
