Find latest RPM in directory

Hi all,

I'm not really a perl programmer, but know that perl and the perl-RPM
package would be really good at finding the latest RPM package among
all those in directory, and printing them out. Does anyone know of an
existing script that can do such a thing?

I'd like to be able to run something like:

# find-latest-pkg openssh-clients

and have it print out only the latest, instead of all ten versions
that may be in the directory. Even better, it would be great to print
out only the latest unique packages in directory, and not have to
specify the package name at all!

Perhaps more applicable to an RPM mailing list, or one specific to
perl-RPM, but hopefully you also consider this linux-admin material.

Thanks so much.
Best regards,
Alex

Re: Find latest RPM in directory

If there are characters like '-' in part of package name you can
improve this script by replacing

=A0for x in `ls -1 | cut -f1 -d '-' | sort | uniq`

=A0with

for x in `ls -1 | sed -e "s/-[0-9]/@/g" | cut -f1 -d '@' | sort | uniq`

so it will cut of part behind dash if there are numbers (version
number) after dash.

Re: Find latest RPM in directory

Hi Herta,

> Would `ls -ltr` do?

No, because I can't rely on timestamps. They may have recently been
copied there. I'd really like to read the RPM headers and let it tell
me which is the latest.

I know you can use perl-RPM to manipulate the --query-format
command-line syntax, which I understand to be the most reliable, but
it's more complicated than I can do.

Thanks,
Alex
