How can i read only third line from a file into a variable in shell script

Question

I am executing a shell script in which I run a sybase query which gives the O/P in a file .

The Output is :-

            tablename

            ---------------------------
            result of query executed my case will be an integer returned


            (Number of rows effected ).

What i want to do is read result of query executed which in my case will be an integer returned into a variable in a shell script . It will be in 3rd line in the file in which i have redirected the Output of my Sybase Query .

How can i do that ?

Answer 1

Did you mean this?

x=`sed -n '3p' inputfile`;
echo $x;

EDIT

Do this.

thirdline=`sed -n '3p' /home/nmsad/abc.txt`;
echo $thirdline;

Answer 2

Try using sed like this:

variable=$(your_script | sed -n '3 p')
