This is a small utility that prints current system tempreatures to stdout. It is intended to be used with status bars like Lemonbar or their wrappers, like succade.

I'm using it to print CPU temperature, which is the common use-case, but the tool should also be able to query other temperature sensors (chips), if available. See usage. temp-sensors is generally pretty similar to the well-known sensors, but tailored for status bars.

temp-sensors uses libsensors to check for available temperature readings. For this, it iterates available chips and their features, looking for the chip and feature names given via -c and -f respectively. Temperature values will be read for all features that match the given feature name, using strstr() (substring search). The temperature values found this way will be added up and, at the end, divided by the number of temperature values found. Only the first chip that matches the given name will be taken into account. If a reading was obtained, it is printed to stdout, including a newline, otherwise temp-sensors does nothing.

• libsensors

• Make sure libsensors-dev and gcc are installed
• Run the included build script

temp-sensors [OPTIONS...] -c CHIP -f FEATURE

• -e use imperial units instead of metric
• -h print usage information, then exit
• -i INTERVAL seconds between checking for a change in value
• -l list all available chips and their features, then exit
• -m keep running and print when there is a visible change in value
• -p PREVISION number of decimal digits to include in the output
• -s print a space between the value and unit
• -t THRESHOLD required change in value in order to print again
• -u add the temperature unit to the output

Note that -c and -f currently use strstr() internally, which means the given string will be searched for in the actual chip/feature name. In other words, -c core will match coretemp, as core is a substring of coretemp. Also note that the string comparison is case sensitive, so core is not the same as Core.
