sed -e 's/\(\s\+\)\?,\(\s\+\)\?/+/g' < file.csv | bcIf you have GNU sed, you can use -r to make this much easier to read:sed -r -e 's/(\s+)?,(\s+)?/+/g' < file.csv | bcYes, this works for floating point too. file.csv: 1,2,3,4,5.5 7,2,3.6666,5,10 Output:15.527.66661,2,3,4,5becomes1,14. @tatsh: Your command just sums the rows, it doesn't match the original command. . @tatsh: I disagree with your comment about perl. OK, it's a bit high-level, but I'm always keen to see as many possible alternatives for these "computational" types of commands. Personally, I too would reach for sed or awk first.perl -e 'for($t=0;;$t++){print chr +($t*($t^$t+($t>>15|1)^($t-1280^$t)>>10))%256}' | play -t s8 -v 0.25 -(play is a symlink to sox; it needs to be invoked that way, this should come with your installation of sox) Yes this could be (very similarly) done in awk but few could read it in one line very easily by comparison.
