Sort a file line by line alphabetically

z y x
c b a

desired output:
x y z
a b c

I don't want to sort the lines into this:
a b c
x y z

nor this:
c b a
z y x

The number of fields per line and number of lines is indeterminate. The field separator is always a space.

Thanks for the use of your collective brains. Smilie

My homework was never this much fun. You have to do this all in bash or what exactly?

PHP Code:

use strict;

my $line = <STDIN>) {
join(" "sort(split(/\s+/, $line))) . "\n";

I've studied the sort docs and tried many combinations without success.

I'm sure I could muddle my way through with a python script, but I was hoping to get a one-liner using a "sort" or similar utility.

This exercise is really just a puzzle I came up with while reading the Vim docs on filters. I was trying to sort a range of lines, then I asked myself if I could just sort the current line.

I'm not a student in any classes, just a student of life.

I responded to your question but I included a link, so I guess it's being held up for administrator review. Anyway, I've tried "sort" and some awk, but still no joy.

The old split sort join trick. Nice. Thanks.
