How to check cpu temperature with script or command

[malikawan]

Any way to check cpu temperature with script or command. I am using lm-sensor but it don't detect any sensor. Is there any setting after installing lm-sensor utility

How about this.
Not using lmsensor just regular linux commands.
Temp in Celsius with 2 decimals.

Code: (bash) [Select]

echo $'scale=2\n'$(cat /sys/class/thermal/thermal_zone0/temp)/1000 | bc

Did you install the hwmon extension? Without that, you won't get cpu temp.

[malikawan]

cat: /sys/class/thermal/thermal_zone0/temp: No such file or directory
sh: cat:: not found

Yes, run:

Code: [Select]

sudo sensors-detect

Persistency:
Add  /etc/sysconfig/lm_sensors  to your backup.
Check  /etc/sysconfig/lm_sensors  for what modules are needed.
Load those modules in  /opt/bootlocal.sh .
For example:

Code: [Select]

modprobe coretemp

Another attempt:

Code: [Select]

#!/bin/sh
for i in /sys/class/hwmon/hwmon*
do
[ -e "$i"/temp*_label ] && LABEL="$(cat $i/temp*_label)" || LABEL="$(cat $i/name)"
TEMP="$(( $(cat $i/*_input) / 1000 ))"
echo -e "$LABEL: \t$TEMP°C"
done
