I tried using bith versions of the script.
/tmp/make-first-existing-target: Joey's latest script
/tmp/make-first-existing-target-1: Olly's script using -q
These work""
--8<---------------cut here---------------start------------->8---
/tmp/make-first-existing-target clean distclean -- -f debian/rules
/tmp/make-first-existing-target-1 clean distclean -- -f debian/rules
/tmp/make-first-existing-target foo clean -- -f debian/rules
--8<---------------cut here---------------end--------------->8---
This correctly runs clean.
The following fails, however it does produce a listing of
available targets:
--8<---------------cut here---------------start------------->8---
/tmp/make-first-existing-target-1 foo clean -- -f debian/rules
dh foo --parallel --with autoreconf
dh: Unknown sequence foo (choose from: binary binary-arch binary-indep build
build-arch build-indep clean install install-arch install-indep)
debian/rules:9: recipe for target 'foo' failed
make: *** [foo] Error 255
[1] 28568 exit 2 /tmp/make-first-existing-target-1 foo clean -- -f
debian/rules
--8<---------------cut here---------------end--------------->8---
