Dojo: Sum a Column
MediumOne-Liner Dojo5-10 minThe brief
The file /root/nums.txt has one integer per line. In ONE line, compute their TOTAL and write just the number to /root/answer.txt.
This is where awk earns its keep: it can accumulate across lines and print a result at the END. No paste/bc gymnastics needed.
What you'll do
- Write the sum of the integers in /root/nums.txt to /root/answer.txt, in one line
Hands-on lab: you work on a real Linux box in your browser, graded on the machine's actual state.
