App::Whiff - find the first executable of a series of alternatives
version 0.008
This module implements logic used by the
whiff command, which takes a
number of command names and returns the first one that exists and is
executable.
This library should run on perls released even a long time ago. It should work
on any version of perl released in the last five years.
Although it may work on older versions of perl, no guarantee is made that the
minimum required version will not be increased. The version may be increased
for any reason, and there is no promise that patches will be accepted to lower
the minimum required perl.
my $filename = App::Whiff->find_first(\@names);
Given an arrayref of command names (which should
not be anything other
than base filename), this method either returns an absolute path to the first
of the alternatives found in the path (using File::Which) or false.
This method is called by the
whiff program to ... well, run.
