Results in files named by tab separated arguments. Save the output Save the output into files. The files will be stored in a directory tree
into files. The file names will be prefixed with I<prefix> which can rooted at I<prefix>. Within this directory tree, each command will result
contain a path with a prefix string. The file with output from stdout in two files: I<prefix>/<ARGS>/stdout and I<prefix>/<ARGS>/stderr, where
(standard output) will prefixed with 'I<prefix>stdout'. The file <ARGS> is a sequence of directories representing the header of the input
with output from stderr (standard error) will prefixed with source (if using B<--header :>) or the number of the input source and
'I<prefix>stderr'. corresponding values.
The postfix is the header of the input source (if using B<--header :>)
or the number of the input source followed by the value of the input
source. This is repeated for every input source and is separated by
TAB (\t).
