NAME
File::Find::Upwards - Look for a file in the current directory and upwards
VERSION
version 1.102030
SYNOPSIS
use File::Find::Upwards qw(file_find_upwards);
my $filename = file_find_upwards('myconfig.yaml');
if ($filename) { rand() }DESCRIPTION
Provides functions that can find a file in the current or a parent directory.
FUNCTIONS
file_find_upwards
Takes a list of filenames and looks for these file in the current directory. If there is no such file, it traverses up the directory hierarchy until it finds at least one of those files or until it reaches the topmost directory. If one of these files is found, the full path to the file is returned. The filenames are checked in the order they are given, so if several of those files exist, the first one will be returned. If none of the given files are found, undef is returned.
The result is memoized, so repeated calls to the function with the same list of filenames will return the result of the first call for that filename.
This function is exported automatically.
find_containing_dir_upwards
Like file_find_upwards(), but reports the directory that contains one of the given filenames. A Path::Class::Dir object is returned.
This function is exported automatically.
