使用sed从字符串中删除美元符号和逗号

Question

sorry if this has been posted in some form already. I cannot find anything that exactly answers my question.

Im new to awk, sed, and bash. And I need to figure this out for a class project.

I have a text file separated by commas, with all the data inside double quotes.

Example piece:

,"CHADWICK R GORE","C00538975","2012","$10,000.00",,"$10,000.00",,,"$5,000.00",,,"$15,000.00",,,,,,,,,,,,,"$15,000.00","$15,000.00",,,,

I need to remove the dollar signs and commas from the fields with money in them. I used sed to do it. My sed code:

s/"\$\([^,"]*\),/"$\1/g 
s/"\$\([^"]*\)"/\1/g

This seems to be wrong, and isn't getting rid of all the commas if there are two in the number.

Any help would be appreciated! Thanks

Answer 1

this line does the job:

awk -F'"' -v OFS="\"" '{for(i=1;i<=NF;i++)if($i~/^\$[0-9.,]+$/)gsub(/[$,]/,"",$i)}1'

the output from your example text is:

,"CHADWICK R GORE","C00538975","2012","10000.00",,"10000.00",,,"5000.00",,,"15000.00",,,,,,,,,,,,,"15000.00","15000.00",,,,
