=head1 NAME
Util::Cmd - Additional Unix Commands needed by SC
=head1 SYNOPSIS
use Util::Cmd qw(:all);
my $grubpath = which('grub');
deltree("/tmp/file1");
deltree("/tmp/directory");
mkpath("/tmp/tmp2/tmp3");
=head1 DESCRIPTION
Exports I<which()>, I<deltree()> and I<mkpath()> functions.
I<which> takes an executable and returns the path to it.
I<deltree> recursively deletes files and directories given a list of
such files and directories.
Note: I<deltree> does not recognize shell metacharacters such as "*"
and "?" so if you want do send it a list of files use something like:
deltree(glob("files*"));
I<mkpath> takes a directory and creates it, along with all the intermediate directories as needed. Acts exactly like "mkdir -p".
=head2 EXPORT
None by default. With the I<:all> specification I<which>, I<deltree>,
and I<mkpath> are exported.
