Create md5 sums and archive the resulting md5 files
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.
I worked out a clumsy solution such as:
but I am not satisfied by the result since:
1- it actually writes the temporary md5 files that I need to remove after the archive is done
2- it is clumsy
I feel that this whole thing can be wrapped in a single line command, but fail to see how to do.
Any help would be appreciated.

Hi,
how can one find that which encryption algorithm the system is using for keeping the user password in the /etc/passwd or /etc/shadow file.
Is it
1: Hashing ( which considers only first 5 letters of password)
2: MD5 (Which allows arbitry length passwords)
Thanks,

bzip2 to compress the archive
and md5 again for the compressed archive.
I send the file to my backup machine.

I am a newbie in programming in Perl.
My problem is that this unix command is embedded in Perl but it gives an empty output. Here's the code:

The output file should contain the md5 hash value of the... (2 Replies)
On my website I host a lot of files, and when people view the site, currently each time the page loads, I have PHP generating the md5 sums for the files right then and there. It was fine when my site was small, but now that's obviously very inefficient. Now I'd like to start generating MD5 sums... (4 Replies)

ar
AR(1) General Commands Manual AR(1)NAME
ar - archive and library maintainer
SYNOPSIS
ar key [ posname ] afile name ...
DESCRIPTION
Ar maintains groups of files combined into a single archive file. Its main use is to create and update library files as used by the
loader. It can be used, though, for any similar purpose.
Key is one character from the set drqtpmx, optionally concatenated with one or more of vuaibcl. Afile is the archive file. The names are
constituent files in the archive file. The meanings of the key characters are:
d Delete the named files from the archive file.
r Replace the named files in the archive file. If the optional character u is used with r, then only those files with modified dates
later than the archive files are replaced. If an optional positioning character from the set abi is used, then the posname argument
must be present and specifies that new files are to be placed after (a) or before (b or i) posname. Otherwise new files are placed
at the end.
q Quickly append the named files to the end of the archive file. Optional positioning characters are invalid. The command does not
check whether the added members are already in the archive. Useful only to avoid quadratic behavior when creating a large archive
piece-by-piece.
t Print a table of contents of the archive file. If no names are given, all files in the archive are tabled. If names are given,
only those files are tabled.
p Print the named files in the archive.
m Move the named files to the end of the archive. If a positioning character is present, then the posname argument must be present
and, as in r, specifies where the files are to be moved.
x Extract the named files. If no names are given, all files in the archive are extracted. In neither case does x alter the archive
file.
v Verbose. Under the verbose option, ar gives a file-by-file description of the making of a new archive file from the old archive and
the constituent files. When used with t, it gives a long listing of all information about the files. When used with p, it precedes
each file with a name.
c Create. Normally ar will create afile when it needs to. The create option suppresses the normal message that is produced when
afile is created.
l Local. Normally ar places its temporary files in the directory /tmp. This option causes them to be placed in the local directory.
FILES
/tmp/v* temporaries

If the same file is mentioned twice in an argument list, it may be put in the archive twice.
