command line support

[kkshethin]

I am using Fedora16 (64 bit). I have installed yum-plugin-local, which collects all rpm packages in directory /var/lib/yum/plugins/local. This directory contains more then one version of rpm packages.

1st question

I want to copy latest packages to another directory. I tried different options of grep but failed. I am not very familiar with command line. so my question is

How can I copy latest versions of rpm packages from /var/lib/yum/plugins/local to another directory?

2nd question

I copied all rpms from dvd to /var/lib/yum/plugins/local and run createrepo. Now I think I can copy latest packages which will be "yum list installed" to another directory. Again i failed with grep. So my question is

How can I copy all latest packages with the help of "yum list installed" from /var/lib/yum/plugins/local to another directory?

I have asked very few questions in last two year and I take these opportunity to express my greatfulness to Fedora, such a nice linux distribution and to all forummembers.

Thanks once again.

If you want to do something for each filename that matches an installed package, one way to do that is to use a shell for ... done loop like the following. Save this as a file, make it executable, then run it.

#!/bin/bash

cd /var/lib/yum/plugins/local

for file in *.rpm ; do
    pkg="${f%.rpm}"
    if rpm -q "$pkg"; then
        echo "I have found an installed packaged %pkg (filename $file)"
        # enter suitable commands here to do the move command that you want
    else
        echo "The filename $file does not match an installed package"
    fi
done

i have tried. It gives error for all packages as below

The filename a52dec-0.7.4-15.fc11.x86_64.rpm does not match an installed package

Looking at the script I gave you, I made a typing error: change the line starting "pkg=" to

pkg="${file%.rpm}"

(otherwise the variable pkg is always empty).

thanks for the script. I have added following copy command but it is not working preperly. It copies one package and while copying another package, it deletes earlier. i do not know what is wrong.

cd /var/lib/yum/plugins/local

for file in *.rpm ; do
pkg="${file%.rpm}"
if rpm -q "$pkg"; then
echo "I have found an installed packaged %pkg (filename $file)"
# enter suitable commands here to do the move command that you want
cp "$file" /media/kks/local
else
echo "The filename $file does not match an installed package"
fi
done

please help

The only thing I can think is that /media/kks/local is not a directory (then the cp command will repeatedly overwrite it).

Make sure you have done

mkdir -p /media/kks/local/

as root, and perhaps change that "cp" line to

cp "$file" /media/kks/local/

to stop cp regarding the target as a file to overwrite.

Remove the quotes from around $file in your cp command.

PHP Code:

cp $file /media/kks/local

i corrected it to (I took some from both )

cp $file /media/kks/local/

now it works.

Thanks for script/tips. thank you both.

today from another thread "http://www.redhat.com/archives/rhl-list/2007-July/msg03527.html"

i found this

Check out repomanage from yum-utils. You could use it something like
this to move old packages to an archive dir (or remove them):

repo=/path/to/cache
archive=/path/to/archive
repomanage --old $repo | while read package; do
mv "$package" $archive
done.

I will try this also & report.

I also found out from "http://blog.kagesenshi.org/2007/01/howto-mirroring-yum-repositories-using.html"

Repomanage
Repomanage is a utility for repository managers to manage old and new packages in a repository. It will read the RPM packages in the directory and list out old/new packages from the directory to stdout.

Example of using repomanage for removing old packages in the current directory and its subdirectories.

repomanage --old . |xargs rm -rf
