Home’s directory is actually /home//

Maybe try doing this command instead:
dpkg –get-selections > ~/backup/installed-software.log

sed -r –in-place ‘s/-[0-9][a-z 0-9_.-]*//’ installed-software.log

sed -r –in-place ‘s/-[0-9][a-z 0-9_.-]*//’ installed-software.log

sed -r –in-place ‘s/-[0-9][a-z 0-9_.-]*//’ installed-software.log

This removes any version dist and architecture information leaving only the packagename suitable for yum to consume using the command as suggested by rainmaker:

cat installed.log |xargs yum -y install

After searching for intensely on the web for ways to retrieve a list of packages that had been manually installed in CentOS 5 (so I can clean up no longer needed apps), I finally had to give up: It’s just not possible – the only thing you can get is useless lists which include gazillion dependencies as if they were programs you had actually ‘installed’.

In RHEL/CentOS/SL 6.x, the situation has gotten slightly better with yumdb.

But IMHO you can ONLY _manually_ generate a list if you do
yumdb search installed_by 0 (lists everything installed by user root, not including things from the initial installation)

and then remove (by hand) everything that isn’t also in the following list
- yumdb search reason user (everything that wasn’t installed as part of a dependency. This however also includes everything from the initial installation)

If you then manually generated a list from those 2 outputs, you should get a list of individual apps that have been installed. To get yum to also remove non-needed dependencies you of course also have to add clean_requirements_on_remove=1 to /etc/yum.conf.

Alternative:
If you run an OS with good package management, such as Gentoo things are so much simpler: edit /var/lib/portage/world and remove what you no longer need, then run emerge –depclean and you’re done.

If anyone gets a permission denied error when running the dpkg –get-selections > /etc/installed-applications.log command

First create your .log file in your chosen folder, give yourself or root full permission to write to the file then run it again.

What I then did was I added this command to the FTPbackup.sh script also posted on this site so now it does this automatically everyday making sure I have a complete up to date list of applications installed.

Any ideas?


#!/bin/bash

## Installed Software Dump
## by SwiftLayer.com

## Dump the list of installed software ##
yum list installed | awk '{print $1}' > software

## Strip out the arch with sed replace ##
sed -i 's/.noarch//g' software
sed -i 's/.i386//g' software
sed -i 's/.i686//g' software

## Strip out the lines we dont want ## sed -i '/ /d' software
sed -i '/Installed/d' software
sed -i '/MySQL/d' software
sed -i '/mysqlclient/d' software
sed -i '/ftp/d' software
sed -i '/dummy-centos-4/d' software
sed -i '/sendmail-cf/d' software
sed -i '/sendmail-doc/d' software
sed -i '/http/d' software
sed -i '/indexhtml/d' software
sed -i '/bind/d' software
sed -i '/postgresql/d' software
sed -i '/gpg/d' software
sed -i '/x11/d' software
sed -i '/caching-nameserver/d' software
sed -i '/yum/d' software
sed -i '/da_/d' software

Then use this to install on other system:

#!/bin/bash

## Yum install from list
## by SwiftLayer.com

if [ ! -e "software" ]; then
echo -e "\n\nSoftware list missing please make sure file 'software' exists\n"
echo -e "hint: run Installed Software Dump 'getInstalled.sh' on old system\n"
echo -e "then copy the 'software' file to this system\n\n"
exit
fi

## Lets pipe in the software list to a single yum command using 'tr' ##
yum install $(cat software | tr '\n' ' ')


cat installed-software.log | xargs yum -y install

You shoud use:
rpm -qa –queryformat “%{NAME}\n” > packages.log

The problem is that I’ve just figure out this, just when I’ve formatted and installed a newer version of Fedora. Is there a trick to use the list I have? because there is no pattern at all to use sed/awk, isn’t it?

is there any other way to automate the process?

please helpme……………………

ks.cfg extracted/edited from a fedora distro /root/anaconda-ks.cfg

for rpm:

%post
for i in $(cat /some_network/kickstart_server/installed-software.log) ; do
packages+=”$i ” ; done
yum install -y $packages
%end

Just an idea so correct me if i am wrong. That saves time. ;-)
