LEOCHARRE::Digest - quick md5 sum output
use LEOCHARRE::Digest ':all'; my $abs = '/home/myself/data.txt'; my $sum = md5_cli($abs);
This is a wrapper around gnu coreutils md5sum. Is much quicker than some Digest::MD5::File and such.
Arg is path to file on disk. Calls md5sum. Returns undef on failure. If not on disk, md5sum warns. Filename can contain funny chars, we use String::ShellQuote to sanitize.
Will only work on posix, with gnu coreutils.
