developers-reference (11.0.7) unstable; urgency=medium
* best-pkging-practices: recommend "command -v" instead of "which"
(Closes: #904246) and simplify paragraph.
https://www.debian.org/doc/manuals/developers-reference/best-pkging-practices.en.html#best-practices-for-maintainer-scripts
has the full text.
In #904246 Sean Whitton wrote:
Section 6.4 should perhaps recommend `command -v` not `which`, because
Debian Policy 4.1.5.0 allows maintainer scripts to assume SUSv4, which
requires support for `command -v`.
and further on he explained that "command" is a shell builtin for the
most common shells (including dash) while "which" is just a builtin on zsh.
so that's why.
