Running Tar from a Shell Script.

If filenames are stored in a tarball with leading slashes
(as in the first / in /work/dev/foo), then, by default, those files
can only be restored at the same absolute path.  Tar is letting
you know that it is storing filenames without the leading slash,
like work/dev/foo.

Bash expects lines to be terminated with the linefeed (newline, \n)
character.  It looks like your shell script has lines ending in
a CRLF (\r\n).

It's reporting that it can't find a command whose name is a single
carriage return (\r).

Tar is telling you that it can't find /work/dev/\r.

You need to remove the \r characters at the end of your lines.
Most likely your editor has a command or mode to do that.
