To get all the lines from a slurped input file to show up as a single line on output, you want something like this: 
perl -e 'undef $/; $_=<>; tr/\n/ /; s/ $/\n/; print'  list

Or you could just use unix/linux commands that do the same thing: 
xargs echo -n < list

[download]
(If you want a clean line break at the end of that output, add  && echo at the end.)
