I executed a command at a Linux machine, and it produced a long output. I did the filtering, and now I have a column of numbers. Now, how do I calculate sum of these numbers? If you have awk available at your machine, here's how to do it.
$ your_long_list_of_command | awk '{ sum+=$1 } END { print sum}'
$ your_long_list_of_command | awk '{ sum+=$1 } END { print sum}'
