Hi and thank to all of you responding. My explanation and understanding:
myfile.txt example: Hello guys <= one space here Anybody from Europe? <= two spaces between Anybody and from tr -c "[:alpha:]" "\n" < myfile.txt myfile.txt is INPUT tr finds the complement to :alpha: and replaces them by \n, resulting in: START-OF-FILEmyfile txt Anybody from Europe EOF Should I have included -s, it would have removed multiple occurences of \n from the OUTPUT and the result would have been: myfile txt Anybody from Europe EOF As the tr(1) states: This (the squeeze) occurs AFTER all deletion and translation is completed. So I still believe there should be OUTPUT in the -s description. I will use this unimportant topic to learn how one can "send diffs". Sincerely, Tomas
