Need to substitue space with \n

Shell Programming and Scripting
1

I have a file with a single line in it as below.

field1 field2 field3

Different fields separated by spaces. I need the output as below.

field1
field2
field3

Any sed/awk solution you can suggest?

2

cat <filename> | sed 's/ /\n/g'

3

The output of sed 's/ /\n/g' is like below.

field1nfield2nfield3

I'm working in AIX. ksh is the shell.

4

Try:

tr " " "\n"

tr works. But I'm trying to see if there are other solutions, especially sed.

Why is the sed 's/ /\n/g' not working for me?

This depends on the sed you are using, with the traditional seds you can't do that.
You can achieve this as follow (in 2 lines!):

sed 's/ /\
/g'

@Franklin,

It works for me!! I guess I'm using a traditional sed!!

Thanks!!
