But uniq eliminates consecutive (neighboring) duplicates only. If, for example,
"Eduardo De Filippo" also occurs at 2nd line, then there would still be 2
separate Eduardo's left. So, sort + uniq is necessary as in,

sort list-file | uniq | sed s/$/,/ | tr '\n' ' '

or you can combine them into one (as tomas already suggested)

sort -u list-file | sed s/$/,/ | tr '\n' ' '
