Hey Guys.
Here is another issue I'm struggling with:
I need wget to download only the files that has been changed. I use md5deep to generate the check sum files.
Here is a simple result; I'll call it $string for the example
if I set -- $string, i can access each argument by using $# (where # is 1,2,3,etc..)
so:
echo $1 will print 0ce73169b069d11e38d6bd78796839c0
echo $2 will print md5data
however I'm not sure how to write $# in a for loop that will go through all of them.
So here is the logic of the loop I'm trying to create:
Any suggestions (or better ways to check md5 files and download only the files that are different?)
I'm trying to write a script that will look in an /exports folder for the oldest export file and move it to a /staging folder. "Oldest" in this case is actually determined by date information embedded in the file names themselves.
Also, the script should only move a file from /exports to... (6 Replies)

Hello everyone,
I am looking to basically creating md5sum files for all iso files in a directory and archive the resulting md5 files into a single archive in that very same directory.

digest::md5::file
File(3pm) User Contributed Perl Documentation File(3pm)NAME
Digest::MD5::File - Perl extension for getting MD5 sums for files and urls.
SYNOPSIS
use Digest::MD5::File qw(dir_md5_hex file_md5_hex url_md5_hex);
my $md5 = Digest::MD5->new;
$md5->addpath('/path/to/file');
my $digest = $md5->hexdigest;
my $digest = file_md5($file);
my $digest = file_md5_hex($file);
my $digest = file_md5_base64($file);
my $md5 = Digest::MD5->new;
$md5->addurl('http://www.tmbg.com/tour.html');
my $digest = $md5->hexdigest;
my $digest = url_md5($url);
my $digest = url_md5_hex($url);
my $digest = url_md5_base64($url);
my $md5 = Digest::MD5->new;
$md5->adddir('/directory');
my $digest = $md5->hexdigest;
my $dir_hashref = dir_md5($dir);
my $dir_hashref = dir_md5_hex($dir);
my $dir_hashref = dir_md5_base64($dir);
DESCRIPTION
Get MD5 sums for files of a given path or content of a given url.
EXPORT
None by default. You can export any file_* dir_*, or url_* function and anything Digest::MD5 can export.
use Digest::MD5::File qw(md5 md5_hex md5_base64); # 3 Digest::MD5 functions
print md5_hex('abc123'), "
";
print md5_base64('abc123'), "
";
OBJECT METHODS
addpath()
my $md5 = Digest::MD5->new;
$md5->addpath('/path/to/file.txt')
or die "file.txt is not where you said: $!";
or you can add multiple files by specifying an array ref of files:
$md5->addpath(@files);
adddir()
addpath()s each file in a directory recursively. Follows the same rules as the dir_* functions.
my $md5 = Digest::MD5->new;
$md5->adddir('/home/tmbg/')
or die "See warning above to see why I bailed: $!";
addurl()
my $md5 = Digest::MD5->new;
$md5->addurl('http://www.tmbg.com/tour.html')
or die "They Must Be not on tour";
file_* functions
Get the digest in variouse formats of $file. If file does not exist or is a directory it croaks (See NOFATALS for more info)
my $digest = file_md5($file) or warn "$file failed: $!";
my $digest = file_md5_hex($file) or warn "$file failed: $!";
my $digest = file_md5_base64($file) or warn "$file failed: $!";
dir_* functions
Returns a hashref whose keys are files relative to the given path and the values are the MD5 sum of the file or and empty string if a
directory. It recurses through the entire depth of the directory. Symlinks to files are just addpath()d and symlinks to directories are
followed.
my $dir_hashref = dir_md5($dir) or warn "$dir failed: $!";
my $dir_hashref = dir_md5_hex($dir) or warn "$dir failed: $!";
my $dir_hashref = dir_md5_base64($dir) or warn "$dir failed: $!";
url_* functions
Get the digest in various formats of the content at $url (Including, if $url points to directory, the directory listing content). Returns
undef if url fails (IE if LWP::UserAgent's $res->is_success is false)
my $digest = url_md5($url) or warn "$url failed";
my $digest = url_md5_hex($url) or warn "$url failed";
my $digest = url_md5_base64($url) or warn "$url failed";
SPECIAL SETTINGS
BINMODE
By default files are opened in binmode. If you do not want to do this you can unset it a variety of ways:
use Digest::MD5::File qw(-nobin);
or
$Digest::MD5::File::BINMODE = 0;
or at the function/method level by specifying its value as the second argument:
$md5->addpath($file,0);
my $digest = file_md5_hex($file,0);
UTF8
In some cases you may want to have your data utf8 encoded, you can do this the following ways:
use Digest::MD5::File qw(-utf8);
or
$Digest::MD5::File::UTF8 = 1;
or at the function/method level by specifying its value as the third argument for files and second for urls:
$md5->addpath($file,$binmode,1);
my $digest = file_md5_hex($file,$binmode,1);
$md5->addurl($url,1);
url_md5_hex($url,1);
It use's Encode's encode_utf8() function to do the encoding. So if you do not have Encode (pre 5.7.3) this won't work :)
NOFATALS
Instead of croaking it will return undef if you set NOFATALS to true.
You can do this two ways:
$Digest::MD5::File::NOFATALS = 1;
or the -nofatals flag:
use Digest::MD5::File qw(-nofatals);
my $digest = file_md5_hex($file) or die "$file failed";
$! is not set so its not really helpful if you die().
