Different versions of UNIX handle the stripping of newlines in a string differently. Obviously if you echo a string, the shell automatically expands newlines “n”.
sed and tr don’t appear to like performing these substitutions. But with Perl its a steal. 🙂
% echo 'hello worldnhello worldntest it' | perl -ane 's#\n# #g; print,"";'
hello world hello world test it
