If I mark several files in dired and press !, I can execute:
rsync -av * jw:/srv/ftp/pub
I can also run:
rsync -av * jw:/srv/ftp/pub &
But if I type &, I cannot run:
rsync -av * jw:/srv/ftp/pub
Because this is equivalent to:
rsync -av * jw:/srv/ftp/pub * &
It actually decribes this behavior in the docstring: with the & command, if no
& appears at the end of the line (which makes little sense, since I pressed &
to indicate it was asynchronous), Dired adds "* &". ??
I think that the following equivalence should hold:
! COMMAND & == & COMMAND
The fix is simply to change the two lines in `dired-do-async-shell-command'
which append " *" to the end of the line to read:
(unless (string-match "[ \t][*?][ \t]" command)
(setq command (concat command " *")))
Thanks,
John
