The GNU coreutils manual gives some example applications such as collapsing multiple newlines into one (tr -s '\n'), or putting each word on its own line while removing punctuation at the same time (tr -cs '[:alnum:]' '[\n*]').

    < text.txt tr -s ' ' | cut -d' ' -f 4 is shorter: it leaves out the unnecessary second argument to tr and the UUOC.
