Hi all,
I have one source pdf file source.pdf, that I want to use pdftk to
split into multiple files such that the n-th file on the target list
is the n-th page from source.pdf
TARGETS = "foo.pdf bar.pdf more_foo.pdf ... "
What I want, is to have a rule like this:
${TARGETS} : source.pdf
pdftk A=$? cat A# output $@
where # is the position of $@ inside the list ${TARGETS}. I see a lot
of buildin pattern matching and substitution functions, but I don't
see anything that help find the matching position.
Any idea?

MZ,
Untested massive overkill
pdftk A=$? cat A$(( echo ${TARGETS} | tr '[[:space:]]' '\n' | grep -vE ^$
| grep -ix $@ | cut -d: -f1 )) output $@
but you might be better writing a helper app to do it for you.
HTH,
