What Others Think

Not bad, but there's one possible problem. If the database fields contain quotes ", then the csv will be corrupt. To fix this, prefix your sed statement with: sed 's/"/""/g' Also, the two sed statements to add quotes to the beginning and end can be combined (simplified) to: sed 's/.*/"\0"/' Finally, I don't understand when I'd need the last sed part: sed 's/\n//g' Combining the lot, I get: ... | sed 's/"/""/g;s/\t/","/g;s/.*/"\0"/' > ...
