If we have a text file which contains numbers along with other data and we have to find the sum of those numbers , then AWK
would come in handy.
Ex:file.txt
10,Ajit 20,Sumit 22,Sam 35,john
If the file contains above data , we could use AWK to find the sum of the number as specified in the below onliner script
awk -F"," '{SUM+=$1} END{print SUM}' file.txt
-F”,” : Specify comma as the delimiter
$1 : contains the first field, which is the number in our case
SUM : Variable storing the sum
END{print SUM}: The code within the END block will be executed after processing is completed on the input data, here we are printing the output
