From sum(1): > sum - checksum and count the blocks in a file $ seq 1 3 | sum 26670 1 I guess 26670 is the checksum and the 6 bytes in the output of seq fit into 1 block... For a SUM() equivalent, I can't think of anything shorter or more convenient than the following while using only standard utils: $ seq 1 3 | awk '{a+=$1}END{print a}' 6
