Is there any hope of supporting the use of the symbolic replacement string that
referred to column names taken from the header line of an input file.
If supported, say with new option --header, you could provide a new example,
such as
EXAMPLE: Use a table as input USING SYMBOLIC REPLACEMENT STRINGS
Content of table_file.tsv:
f1<TAB>f2
foo<TAB>bar
baz <TAB> quux
To run:
cmd -o bar -i foo
cmd -o quux -i baz
you can run:
parallel -a table_file.tsv --header --colsep '\t' cmd -o {f1} -i {f2}
I'm sure there are lots of complications (duplicate names in header, odd
character encoding), and perhaps the need is best met through piping input
through `sed` or `perl`.
I am interested in your perspective. I expect you've already thought about it
and perhaps rejected it....
