Crimeney, but that is ugly.

"Crimony" :-)

I can't figure out what the $'s are for in there.

That's POSIX shell syntax.  A dollar sign followed by a single quote
indicates that the following string up to the matching single quote is
to have C string interpretation applied with respect to backslashes
etc.  (It's not *exactly* C syntax, but close enough.)

OK, previously I have used      tr -d $'\t' |tr -d $'\n' |tr -d $'\r'
which was working fine, but
now I have tried                td -ds '[\n\t\r]' ' '
which does not work.

My try to use                   td -ds $'[\n\t\r]' ' '
ends in a error message
                                Any suggestions ?

Greetings
Michelle
