Shell Programming and Scripting

Hi Experts ,

My requirement is like this ..
I have source comming as 4,234.55
I need and out put = 4234.55
I need to write a sed command ..

I have already used sed command for multiple conditions in a file for replacing comma , double quotes , brackets , retain negative values..
but not able to remove comma for decimal value

Can the code be embeded with the same sed command
Any help would be appreciated

My sed command as of now is this below
sed -e 's/\("[^,]*\)[,]\([^"]*"\)/\1\2/g' test | sed -e ':a' -e 's/\("[^"][^"]*\),\([^"][^"]*"\)/\1\2/;ta' | sed 's/"//g' | sed 's/(\([0-9.][0-9.]*,\{0,1\}[0-9]*\))/-\1/g' > sample

Thanks

Removes comma between two decimal digits:

Code:

sed 's/\([0-9]\),\([0-9]\)/\1\2/g'

Thanks yazu

$ echo "4,234.55" | sed 's,\,,,g'
4234.55
