What Others Think

I like how compact this is, but note that on BSD (which includes OSX), you cannot include "\n" in the replacement string. AFAIK, you have to do this instead: sed 's/,/\ /g;q' /tmp/customer.csv | nl

Here's a better formatted version since I cannot edit my comment above: > sed 's/,/\ /g;q' file.csv | nl Note that you need to literally enter a newline in the shell to continue to the next line of the command.
