I don't seem to understand the NULLCMD function.
Say I have a lot of files I want to move to
/Some/Dir/Somewhere
and I want to drag them to the window and drop them and hit return (after
each one) so that I might drop a file and the path would be
/path/to/real/file.txt
is there a way to use the NULLCMD feature so that if I drop a pathname it
will know that I want to move that file to /Some/Dir/Somewhere?
right now I just get:
zsh: permission denied /path/to/real/file.txt
thanks

It's what gets executed when you redirect output from nowhere, e.g.
zsh% > /some/file
is equivalent to
zsh% $NULLCMD > /some/file
Conversely, READNULLCMD is what gets executed when you redirect input to
nowhere; e.g.
zsh% < /some/file
is equivalent to
zsh% $READNULLCMD < /some/file
Here's a way to fill your disk with foo:
zsh% echo foo > foo
zsh% >>foo <foo

No.
You'd have to start a loop like this:
zsh% while read name; do mv $name /Some/Dir/Somewhere; done
Then you drag, drop, and hit return, until you've moved all the files;
and when done, you type ctrl-D to terminate the loop.

Shame.

:Shame.
Hmmm, worked for me. Probably means it's time to fix my OS's cat, since I
can't think of any applications where this is desirable.
