Find certain line in file and extract part of it
I am trying to make a Bash script that will look in a file for a certain line (
IR Freq. = 23.23) and copy the
23.23 from it and send it through serial interface (ttyS0).
The line will move around the file and the number will change a lot!

you can use the below script
grep -r "IR Freq." filename | cut -d '=' -f 2 | sed -e 's/^[[:space:]]*//'
