How can I replace each newline (\n) with a space using sed?How can I replace each newline (\n) with a space using sed?

... does not work in freebsd 7.2 on the command line:

 ( echo foo ; echo bar ) | sed ':a;N;$!ba;s/\n/ /g' sed: 1: ":a;N;$!ba;s/\n/ /g": unused label 'a;N;$!ba;s/\n/ /g' foo bar

But does if you put the sed script in a file or use -e to "build" the sed script...

 > (echo foo; echo bar) | sed -e :a -e N -e '$!ba' -e 's/\n/ /g' foo bar

or ...

> cat > x.sed << eof :a N $!ba s/\n/ /g eof > (echo foo; echo bar) | sed -f x.sed foo bar

Maybe the sed in OS X is similar.

:a is a label (as pointed out in comments to that answer)

not sure why <pre> ... </pre> around the last chunk doesn't work, try 4 spaces instead and live with the bogus coloring
