SubjectRe: pre-2.0.31-7 nit picks
But without a \c or a -n echo will put a newline on there for you...
(although it might be in two write() statements I guess) Another cevat, I
discovered while piping commands to a VMS box through a telnet session
that it didn't like \n, just \r... I don't know how /proc deals with
linefeed/carriage return, but I had to use:
echo -n -e "xxxxxx\r"
