Hello,
The attached patch adds -t or --target-directory support for split, specifying
in which directory the split files should go into.
The usecase for this when receiving a big file over a network, but you don't
have diskspace for the file itself and its splitted version. Now, you can do
things like this:
cat some_big_file | ssh [EMAIL PROTECTED] split -t /home/bram/tmp/
in order to have some_big_file split out immediately.
Kind regards,
--
