Sort a file line by line alphabetically

H2OBoodle · #1 (**permalink**) 02-09-2008

infile:
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.

what have you tried so far?

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

PHP Code:


			
#!/usr/bin/perl                                                                                                              

use strict;
use warnings;

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

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.

you should show how you did that.
anyway, have a go at it

Code:

awk '
 {
  for(i=NF;i>0;i--){
      # fill in the blanks
  }
 }
' file

Yes, I asked earlier what you had tried so far. That is quite helpful to the people that reply to you because they can get a feel for where you are going wrong or where you can use improvement and also see what you are doing correct and see what shell script you are using. Next time post any code you had written to try and solve the problem.
