“repoquery” is a program for querying information from YUM repositories similarly to rpm queries. The “yum-utils” package should be installed to use this command. If it is not already installed in your system you can install the package by the following yum command.
# yum install yum-utils
The following command lets us to view the dependencies of an already installed rpm package.
# repoquery --requires --resolve [package]
here,
- –requires – List package dependencies.
- –resolve – When used with –requires, resolve capabilities to originating packages.
- package – rpm package name
Example:
# repoquery --requires --resolve nano info-0:5.1-4.el7.x86_64 ncurses-libs-0:5.9-14.20130511.el7_4.x86_64 bash-0:4.2.46-29.el7_4.x86_64 glibc-0:2.17-55.el7_0.3.i686 glibc-0:2.17-106.el7_2.1.x86_64
You can utilize the repoquery command in order to gather a list of packages that are dependencies of a package that you would like to update. Do note that this will grab the latest version of the dependencies even if you specify a version for the package that you are querying
For further information, see the manual page man repoquery or the help text “repoquery –help”.
# man repoquery
# repoquery --help
Resolving dependencies recursively
You can use the –recursive option with “–requires –resolve” option to query packages recursively. For example :
# repoquery --requires --resolve --recursive nano pcre-0:8.32-15.el7_2.1.x86_64 glibc-0:2.17-55.el7_0.3.i686 bash-0:4.2.46-29.el7_4.x86_64 libselinux-0:2.2.2-6.el7.x86_64 basesystem-0:10.0-7.el7.noarch tzdata-0:2014g-1.el7.noarch pcre-0:8.32-15.el7_2.1.i686 libstdc++-0:4.8.2-16.2.el7_0.x86_64 libgcc-0:4.8.2-16.2.el7_0.x86_64 nss-softokn-freebl-0:3.16.2.3-9.el7.x86_64 setup-0:2.8.71-4.el7.noarch ncurses-base-0:5.9-13.20130511.el7.noarch zlib-0:1.2.7-13.el7.x86_64 glibc-0:2.17-106.el7_2.1.x86_64 filesystem-0:3.2-21.el7.x86_64 redhat-release-server-0:7.3-7.el7.x86_64 libsepol-0:2.5-6.el7.x86_64 ncurses-libs-0:5.9-14.20130511.el7_4.x86_64 libgcc-0:4.8.3-9.el7.i686 info-0:5.1-4.el7.x86_64 glibc-common-0:2.17-78.el7.x86_64
Alternate method – yumdownloader
Another way is to use yumdownloader please note though, that this will not grab dependencies of dependencies, so you may still have to run it on further packages down the list until you have all of the requirements.
