Answer 1

IF your data includes an arbitrary sequence of blank characters (tab, space), and you want to replace each sequence with one comma, use the following:

sed 's/[\t ]+/,/g' input_file

or

sed -r 's/[[:blank:]]+/,/g' input_file

If you want to replace sequence of space characters, which includes other characters such as carriage return and backspace, etc, then use the following:

sed -r 's/[[:space:]]+/,/g' input_file

Answer 2

Inside vim, you want to type when in normal (command) mode:

:%s/ /,/g

On the terminal prompt, you can use sed to perform this on a file:

sed -i 's/\ /,/g' input_file

Note: the -i option to sed means "in-place edit", as in that it will modify the input file.

Answer 3

I know it's not exactly what you're asking, but, for replacing a comma with a newline, this works great:

tr , '\n' < file

Answer 4

On Linux use below to test (it would replace the whitespaces with comma)

 sed 's/\s/,/g' /tmp/test.txt | head

later you can take the output into the file using below command:

sed 's/\s/,/g' /tmp/test.txt > /tmp/test_final.txt

PS: test is the file which you want to use

Answer 5

Try the following command and it should work out for you.

sed "s/\s/,/g" orignalFive.csv > editedFinal.csv

Answer 6

If you are talking about sed, this works:

sed -e "s/ /,/g" < a.txt

In vim, use same regex to replace:

s/ /,/g
