   Well, I think almost by definition there isn't a 'most
unixy' way to do much of anything, which is one of the fun things
about the unix command line. 

   But, how about this:  echo `<your command>` | sed -e 's/ /,/g'

 For example, say ls gives this:

 myprompt> ls
afile  bfile  cfile  dfile  theLastFile

 myprompt> echo `ls` | sed -e 's/ /,/g'

gives:
 afile,bfile,cfile,dfile,theLastFile

 myprompt> echo `seq 1 20` | sed -e 's/ /,/g'

  leads to: 
1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20

  Of course, you'll have problems w/spaces if your command
output for one line has spaces in it (e.g. output from grep)...
