Passing parameter in sed or awk commands to print for the specific line in a file

Hi,

I am trying to print a specific line in a file through sed or awk. The line number will be passed as a parameter from the previous step. My code looks as below.
Code:
TEMP3=`sed -n '$TEMP2p' $FILEPATH/Log.txt`

$TEMP2, I am getting from the previous step which is a numerical value(eg:3).

But, i am getting an error as below
Code:
sed: can't find label for jump to `EMP2p'

Kindly, help me on this.


Regards

Whatever $TEMP2p has as value, it can't be substituted inside single quotes '. Either change it to double quotes " or have opening and closing single quotes before and behind the variable.

Thanks Zaxxon! Both the options worked.
