How to insert Line break regex

Question

I have a file which contains one line like this

I want to put a line break after each .CSV file name like so

test1.CSV
test2.CSV
test3.CSV
test4.CSV

Thanks

The tr utility could be used to replace each space by a newline like so:

tr ' ' '\n' <infile >outfile

If there are multiple spaces between the filenames on the line, you may compress the generated newlines into single ones using tr -s.

This obviously assumes that none of the filenames contain embedded space characters.

You may also achieve the same affect with sed:

sed 'y/ /\n/' infile >outfile

Use sed:

$ sed 's/ /\n/g' file

where file is the name of the file to be edited.
