Add edited numeric strings in awk
I am using awk to sum up all amounts and at end print total.

input:
10,250.00
20,103.15


expected output:
30353.15

code:
{subtot=+$1} END{print subtot}

The problem I encounter is it stops at commas and returns 30 as answer

And if I use this code:
{subtot=($1+0);subtot=+$1} END{print subtot}

it returns 40

any help, please.

Try

Code:
$ awk '{sum+=$1}END{print sum}' file

if comma is there then use this

Code:
$ printf "%s\n%s\n" 10,250.00 20,103.15 | awk '{gsub(/,/,x,$1);sum+=$1}END{print sum}'
30353.2

Thanks. One more query. Is it possible to assign the result of gsub to a variable?
like
Code:
var=gsub(/,/,"",$1)

you can.
variable will results in to number of times the substitution has been made.
For ex:
Code:
echo "hi,this,is,name" | awk '{ a=gsub(/,/,"");print a}'

10250.00
20103.15

if you assign directly as greet_sed said it gives you a count of substitution

That var will hold the count of substitutions that gsub has made on the string it worked upon. The string itself will be modified and thus holds the result.
