Awk in loopwith different file

I have four files and want to run a awk code on each file. But this code is not working.

My code:

for i in "udp-250b.tr" "udp-50b.tr"
do
awk '
BEGIN {
    //some code
}
{  
    //some code
}
END {
   //some code
} ' i
done

Answer

Awk can work with multiple files no need of for

syntax will be like this

awk '{  }' file1 file2 file3

or

awk '{  }' file*

In your case

awk 'BEGIN{ } { } END{ }' udp-*.tr

To correct your existing code change

} ' i

To

} ' "$i"
