Better way to query packages on a RHEL system?

Working with RHEL 6.8 x86_64 and working to install 3rd party software.

I have to query the default install to confirm what packages are installed and if they are the correct version. I'm basically just typing this command this over and over:

rpm -qa | grep -i "insert package here" >> /tmp/output.txt
Say when I query Python, I got back more packages then I wanted, so I had to do some cleanup of output.txt file.

Is there a better way to go about doing this?

Giving no package name will return ALL installed packages.

What do you expect ? - you used "-a" and a glob .... :sheesh:
If you want just (base) python use "python" in either rpm -q or dnf.

If you are running this a lot, a better idea might be to list the lot to a file and just use grep on that.

In RHEL, there is a package "rpm-cron" that you can install. It will, daily, list all installed packages into file /var/log/rpmpkgs. Running grep on that file is quite fast.

yum list installed "*<partial_name>*"
For example, if you want to see available geany plugins you could run

yum list "*geany*"
will show any packages, installed or not, with "geany" in the package name.

No solution for Redhat, but this is why I always end up back on debian. Basically I don't need to google to find things.

$ # find by filename
$ apt-file find file.h

$ # find by partial package name, even those NOT installed
$ dpkg-query --load-avail -l '*lib*sdl*'
$ # more current method of mostly the same
$ apt-cache search --names-only sdl | grep lib

$ # show specs on a package before you install it
$ apt-cache show alsa-utils

$ # show contents of a package, even those NOT installed
$ apt-file list devscripts
$ # same for the .deb file
$ dpkg -c package.deb

$ # or if you're curious and want to find things randomly with only one command
$ less /var/lib/dpkg/available
$ # although that requires dselect installed and dselect update
$ # to populate the mostly deprecated available file

i prefer
yum provides /usr/lib64/libgimp-2.0*
that will tell you WHAT package to install to get it


package, rhel6
