Printing a string value results not found

Question

When I run my script, there is no output to the terminal.

This my code:

for ((h = 1 ; h < 4 ; h++ )); do 
    x=$(awk -v i=h -v j=17 \'FNR == i {p         


        

Answer 1

You are saying:

awk -v i=h -v j=17 ...

Note i=h which is equivalent to saying: i=0.

It seems that you wanted to say:

x=$(awk -v i=$h -v j=17 'FNR == i {printf "%s ", $j}' newiptables.log)
             ^
             |== refer to the variable h
