Help with cat

Question

Hi, i need help with formating output from text.
For example i have this output:
/dev/sda: WDC WD1600BEVT-22ZCT0: 37°C
And i need format this output to "37°C" only or "/dev/sda" only or "WDC WD1600BEVT-22ZCT0" only.
I know only how i can format output to "/dev/sda" :
cat text.txt | head -c 8
Thanks

Answer 1

This is getting repetitive...
awk '/^charging state/{ print $NF }' /proc/acpi/battery/BAT1/state
sed -n '/^charging state/s/.*:\(.*\)/\1/p' /proc/acpi/battery/BAT1/state
while IFS=':' read label val; do
[[ $label == charging state ]] && { echo $val; exit; }
done < /proc/acpi/battery/BAT1/state
There's many ways to do these things. I advise you to learn a little on your own as it will make your life in linux much easier and more productive.
