[Novalug] remove commas from .csv files

[Nino Pereira]

Hi smart people,

In a directory I have a slew of comma-separated files, each with two columns.
In this same directory, which has nothing else, I want to make new files
wherein the commas are replaced by spaces, and the original file name
foo.csv becomes foo.dat.

Copying from an earlier discussion on this list, I do

sed -e "s/,/   /" foo.csv > foo.dat

and so on, replacing foo by whatever the file names are.

This works. But, being lazy, I'd want to avoid typing all these
file names, so I try

sed -e "s/,/   /" *.csv > *.dat

Now I get one big file called *.dat, which is useless.

What's the right way to do this? Something with if  ... fi no doubt,...

Thank you

Nino
