Most files pertaining to RPM are kept in the /var/lib/rpm/ directory. For more information on RPM, refer to the chapter Chapter 10, Package Management with RPM. The /var/cache/yum/ directory contains files used by the Package Updater, including RPM header information for the system.
Then, what is an RPM file?
But the RPMs that get installed are basically like a zip or tar file. So the contents of these files get dumped into the system and RPM maintains a database of what packages it has installed.
One source claimed that to find detailed information regarding the RPM, such as: version, install date, size, vendor, license, description, etc. use the syntax: rpm -qi [package name] List All Files Installed By Package To list all the files installed by a particular package, use the syntax:.
A query we ran across in our research was “How do I find the path of a downloaded rpm file?”.
Try to search for the name of the file that you downloaded, usually it will be the same name as the RPM only with a different extenstion, if any. If the rpm package that you installed was named “sylpheed-0.6.6-1.i686.rpm”, type “rpm -ql sylpheed-0.6.6-1” and it will show you a listing of all files and their install paths in that package.
What is the difference between rpm and Yum in Linux?
“rpm” runs against the database, “yum” uses the database and the repositories. On most of my systems, yum removes the downloaded packages after they are installed.
Where are environment variables stored linux?
On modern Linux systems, environment values are “kind-of” stored on the stack — for specific values of “kind-of”. The actual strings that make up the environment are stored at the top (highest-numbered addresses) of the process’s virtual address space, along with other environmental data.
An answer is that shell variables are stored in the memory of the running shell. The difference between shell variables and environment variables is that environment variables are placed in the environment of subprocesses.
My chosen answer is environment variables are stored together with command line arguments at the top of the process memory layout, above the stack. Show activity on this post. The environment (name/value pairs) lives towards the top of the stack.
The next thing we wondered was: what are environment variables in Linux?
Environment variables are a manifestation of the shell you’re using. I would imagine that the environment as a whole is a data structure that is part a component of what makes up a process.
All environment variables are shell variables. Thanks for contributing an answer to Unix & Linux Stack Exchange !
Where is linux logical volume metadata stored?
All of these internal data used by LVM are its metadata. They are stored on disk sectors that you cannot see directly. For instance, each LVM Physical Volume has metadata blocks that are used to store information related to how the Volume-Groups are stored on these Physical-Volumes.
How do I backup a logical volume in Linux?
Logical Volume Backup Metadata backups and archives are automatically created whenever there is a configuration change for a volume group or logical volume, unless this feature is disabled in the lvm., and conf file. By default, the metadata backup is stored in the /etc/lvm/backup file and the metadata archives are stored in the /etc/lvm/archive file.
Where is LVM volume group metadata stored?
By default, an identical copy of the metadata is maintained in every metadata area in every physical volume within the volume group. LVM volume group metadata is small and stored as ASCII. Where does LVM store the mapping between logical extents and physical extents?
The LVM metadata contains the configuration details of the LVM volume groups on your system. By default, an identical copy of the metadata is maintained in every metadata area in every physical volume within the volume group.
