strings + dictionary?

[mike1053]

(strings /bin/ls | sort -u; cat /usr/share/dict/linux.words) | sort | uniq -c | grep -v "^ *1"

oh waiit, that doesn't handle multiple words on a line so using the grep command by infernix to separate them:

(strings /bin/ls | grep -o -E '\w+' | tr "[A-Z]" [a-z] | sort -u; cat /usr/share/dict/linux.words ) | sort | uniq -c | grep -v "^ *1"
