linux command for introducing single space after each character in text file

Question

I have a text file and I have to introduce single space after each character. The command that I am using is:

sed 's/./& /g' source.txt>output.txt

But I am not getting the output, output remains same as input. Please help me regarding this. Is this command correct?

external edit: according to the comment below, the input text is: 'pustə́_pɾemí nù_kədé ví_kɪse_pyaːɾe mɪ'

and its corrsponding output is : pustə́_pɾemí nù_kədé ví_kɪse_pyaːɾe mɪ

Instead of introducing single space after each character it is replacing single space(which is already in input)with double space.

If you are using Mac OSX, the sed comes from BSD and not GNU. You can read about differences here: stackoverflow.com/questions/6761361/… — philshem

input is:- pustə́_pɾemí nù_kədé ví_kɪse_pyaːɾe mɪ on executing sed command output is:- pustə́_pɾemí nù_kədé ví_kɪse_pyaːɾe mɪ .It is not introducing space after each character, but replacing single space (which is already in input) with double space. — user77

Your sed command works for me, but the accents on the characters are moved from the character.

Here is a longer sed command that you can try, and it also works for me.

sed 's/\(.\)/\1 /g'

Here is an 'awk' option if 'sed' doesn't work

awk 'BEGIN{FS=OFS=""}{for (i=1;i<=NF;i++) {$i=$i " "}}1' source.txt > output.txt

modified from here

edit: If you are using Mac OSX, 'sed' comes from BSD and not GNU. You can read here instructions how to add a single space and then modify to fit your needs.

It is showing the output but many of the garbage characters are also introduced

output is like this:- p u s t É Ì _ p É Ÿ e m i Ì n u Ì _ k É d e Ì v i Ì _ k É ª s e _ p y a Ë É Ÿ e m É ª and its corresponding input is:- pustə́_pɾemí nù_kədé ví_kɪse_pyaːɾe mɪ

-1 Can you explain why the sed solution doesn't work? This is a heck of a lot more complicated.

I am new to these commands. I don't know , I got somewhere this sed command that I am using.

The encoding may be due to your terminal. Please see here: stackoverflow.com/questions/1820659/…

Your sed command is correct so it appears to me that you are running in to some locale issue.

On the prompt type the following and re-run your command:

LANG="en_US.UTF-8"
