combining two sed -s

Question

$ sed s/,/' '/g file.txt| sed s/'\.'/,/g

I want to replace numbers into the SI format.

ex: 1,000,000.53 would become 1 000 000,53

, becomes ' ' and . becomes ,

Is there a way I can combine this?

Answer 1

You can use the -e flag multiple times with sed to do many replacements at once. They happen in the order they are listed, so as long as you order them correctly, you won't have a situation where . turns into , which then turns into ' '.

sed -e 's/,/ /g' -e 's/\./,/g' file.txt
