# sed to divide a dec number by 10

## sed to divide a dec number by 10

(OP)
Hi to all,

I'm new to sed and would like to know what would be the correct syntax on how to divide the a decimal number by 10 (2nd and 4th column) then the result would be on another file.

Sample Data:

John, 123 ,xxx, 100
David, 223, yyy, 145
Smith, 178, ccc , 240

Result would be:

John, 12.3 ,xxx, 10.0
David, 22.3, yyy, 14.5
Smith, 17.8, ccc , 24.0

Any help would be gladly apreciated....

Thank you

I'd use awk

I'd rather use awk if that would be the solution to my problem....

Thanks.

Thanks for the help. Have tried this solution through awk and it really works.

awk -F ',' '{print $4/10'}' InputFile > OutputFile Tyvm. ### RE: sed to divide a dec number by 10 Just for completeness, here's the sed solution... #### CODE sed 's/$$[0-9]$$$$[0-9]$$$/\1.\2/1'  Infile

It's not really dividing by 10, it's just inserting a decimal. The awk solution is the correct one.
