USER command questions (Fairlight)

[John Esak]

If you're going to use opehdir() as you say with SYSTEM, then do yourself
ahother favor and get rid of the NeXTDIR.. Why "execute" that command for
every file in the folder, when all you have to do is increment a counter and
it automaticlly points to the next file.  I'm missing your logic here.  Or,
maybe I didn't explain the @dirlist arrays wlell nough.

You're assigning the 'move' "alias" (ie., USER handle or whatever the
proper fP parlance for it is) first, there.  And then you're essentially
piping in arguments to it, rather than having them all as one command.

In shell terms, what you're doing is essentially the same as:

$ mv <<END
> -f
> /some/path
END

That's why 'mv' is bailing on you.  It's not meant to be used that way.

Forget using USER for 'mv'.  It's nothing you get interactive feedback
from, so USER is overkill.  Assemble the entire command with arguments and
feed it to SYSTEM for each file.

Also, be VERY careful with dirlist.  It has a filename length limitation
that will bite you if the filenames are longer than the memory allocated to
the function's memory storage.

Back to the original:  Only use USER when you require interactive feedback
from and/or interactive data supply to a process.  Neither 'mv' nor 'cp'
fall into that category.



 
Thanks Mark!  That was exactly the answer I was looking for!  I will stick
with SYSTEM for mv then, and OPENDIR/NEXTDIR for getting the filenames :)
(thanks to John Esak for the demo on how OPENDIR's usage)
