YUM Search Result - How to tell if any of the listed packages are installed?

Akhran · 07-17-2013, 05:08 AM

Debian Aptitude show command has a 'i' next to the package name if it is already installed.

Just wondering if there is a similar indicator or to that effect from the result of 'yum search' result.

Thanks!

Do you need to see a list of packages installed on your system?

yum list installed

Eg. I would like to (1) search for packages related to 'font' and also (2) to know if they are already installed in the system. So I did a 'yum search font' with part of the results as shown below. Objective (1) is achieved, but to know if each of these packages are installed, I would need to do a 'yum listed <package name>' for each of the package listed in the result. Is there a more efficient way?

Thanks again !

You can take the results of the first command I suggested

Code:

sudo yum list installed

and rather than displaying the full list on your screen you can pipe the results into a second command,

Code:

grep fonts

which will then show you only the installed packages on your system with the text string "fonts" in the package name

So the full command is

Code:

sudo yum list installed | grep fonts

I'm not sure if this can be done by using only yum and its options.

You can write a one-liner to mimic the aptitude behaviour:

Code:

yum info *fonts* | awk -F: '/^Name/ { printf $2} /^Repo/ { if ($2 == " installed") { printf " (installed) " } else { printf ""}} /^Summary/ { print $2 }'

The above is based on the output of yum info <string> and only shows those fields you want/need.

The above shows the package name, followed by installed (or empty if not) and the summary. One line per found package.

Output would look something like this (using *system-config* to show both entries possible) :

Code:

 system-config-firewall-tui (installed)  A text interface for basic firewall setup
 system-config-network-tui (installed)  The Network Adminstration Tool
 system-config-date A graphical interface for modifying system date and time
 system-config-date-docs Documentation for setting the system date and time

Ah right, looks like I mis-read the OP slightly, apologies!

Thanks guys for the helpful posts. If only 'Yum search' has those information displayed by default, or with an option...
