NAME¶
App::Whiff - find the first executable of a series of alternatives
VERSION¶
version 0.005
DESCRIPTION¶
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.
METHODS¶
find_first¶
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.
run¶
This method is called by the
whiff program to ... well, run.
