[bug #56855] find -printf %h gives an empty string for the root directory '/'

[Stephane Chazelas]

Follow-up Comment #1, bug #56855 (project findutils):

There is also a case for having the empty string there. If it was the case for
%f as well, that would mean that -printf %h/%f would always be equivalent to
-printf %p

More importantly, in cases like:


find / -name foo -printf '%h/bar\0' |
  xargs -r0 cmd


that means you don't get an incorrect //bar when foo is found in /.

Remember that //foo is not guaranteed by POSIX to be the same as /foo (and in
practice is not on some systems like cygwin).

The :h and :t history modifiers of tcsh and bash (not zsh) do return the empty
string for /
