=item B<--res> I<prefix> (beta testing)
Results in files named by tab separated arguments. Save the output
into files. The file names will be prefixed with I<prefix> which can
contain a path with a prefix string. The file with output from stdout
(standard output) will prefixed with 'I<prefix>stdout'. The file
with output from stderr (standard error) will prefixed with
'I<prefix>stderr'.
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).
Save the output into files. The files will be stored in a directory tree
rooted at I<prefix>. Within this directory tree, each command will result
in two files: I<prefix>/<ARGS>/stdout and I<prefix>/<ARGS>/stderr, where
<ARGS> is a sequence of directories representing the header of the input
source (if using B<--header :>) or the number of the input source and
corresponding values.
E.g:
parallel --header : --results foo/bar echo {a} {b} ::: a I II ::: b III IIII
parallel --header : --results foo echo {a} {b} ::: a I II ::: b III IIII
will generate the files:
foo/barstderr a I b III
foo/barstderr a I b IIII
foo/barstderr a II b III
foo/barstderr a II b IIII
foo/barstdout a I b III
foo/barstdout a I b IIII
foo/barstdout a II b III
foo/barstdout a II b IIII
foo/a/I/b/III/stderr
foo/a/I/b/IIII/stderr
foo/a/II/b/III/stderr
foo/a/II/b/IIII/stderr
foo/a/I/b/III/stdout
foo/a/I/b/IIII/stdout
foo/a/II/b/III/stdout
foo/a/II/b/IIII/stdout
and
parallel --results foo/bar echo {1} {2} ::: I II ::: III IIII
parallel --results foo echo {1} {2} ::: I II ::: III IIII
will generate the files:
foo/barstderr 1 I 2 III
foo/barstderr 1 I 2 IIII
foo/barstderr 1 II 2 III
foo/barstderr 1 II 2 IIII
foo/barstdout 1 I 2 III
foo/barstdout 1 I 2 IIII
foo/barstdout 1 II 2 III
foo/barstdout 1 II 2 IIII
where all spaces are TABs (\t);.
