How to save command input & output to same file

Hey All,

In general, I'm moving mailman lists to Google Groups. I have saved a list of the lists to lists.txt and have generated a list of list owners to listOwners.txt using:

Code:

xargs -a lists.txt -I % list_owners % >> listOwners.txt

I've unsuccessfully searched for a 1 line bash command that will save the name of the list (the input) and the list owner(s) (the output) to the same file, preferably on the same line. A list may have multiple owners.

Thanks In Advance,

Split to multiple lines for readability:

Code:

 while read a ; do for o in `list_owners $a` ; do 
   echo $a $o >>listOwners.txt ; done ;done <lists.txt
