This article mainly introduces the practical zypper commands in linux, which are very detailed and have certain reference value. Friends who are interested must finish reading them.

Suse Linux uses zypper for package management, which is a package management system provided by the ZYpp package management engine.

The zypper command with no arguments lists all the available options, which is much easier to use than referring to the detailed man manual.

How to use zypper to install packages

Zypper installs packages on your system through the in or install subcommand. It is used the same as the yum package installation. You only need to provide the package name as a parameter, and the package manager (in this case, zypper) will handle all dependencies and install it with the package you specify.

# zypper install telnetRefreshing service 'SMT-http_smt-ec2_susecloud_net'.Refreshing service' cloud_update'.Loading repository data...Reading installed packages...Resolving package dependencies... The following NEW package is going to be installed: telnet 1 new package to install.Overall download size: 51.8 KiB. Already cached: 0 B.

[done] Checking for file conflicts:.... ... [done] (1amp 1) Installing: telnet-1.2-165.63.x86_64. .... [done]

The above is the output when we installed the telnet package for your reference.

How to use zypper to remove a package

To erase or remove a package in Suse Linux, use the remove or rm subcommand that comes with zypper.

Root@kerneltalks # zypper rm telnetLoading repository data...Reading installed packages...Resolving package dependencies... The following package is going to be REMOVED: telnet 1 package to remove.After the operation, 113.3 KiB will be freed.Continue? [y/n/...? Shows all options] (y): y (1Acer 1) Removing telnet-1.2-165.63.x86_64. .. [done]

We remove the previously installed telnet package here.

Use zypper to check dependencies or authenticate the integrity of installed packages

Sometimes you can install a package by forcing you to ignore dependencies. Zypper enables you to scan all installed packages and check for dependencies. If any dependencies are missing, it will give you the opportunity to install or reinstall it, thus maintaining the integrity of the installed package.

Use the zypper command with the verify or ve subcommand to check the integrity of the installed package.

Root@kerneltalks # zypper veRefreshing service 'SMT-http_smt-ec2_susecloud_net'.Refreshing service' cloud_update'.Loading repository data...Reading installed packages... Dependencies of all installed packages are satisfied.

In the above output, you can see the * line indicating that all dependencies of the installed package are fully installed and no more action is required.

How to use zypper to download packages in Suse Linux

Zypper provides a way to download the package to a local directory without installing it. You can use this downloaded package on other systems with the same configuration. The package is downloaded to the / var/cache/zypp/packages/// directory.

Root@kerneltalks # zypper download telnetRefreshing service 'SMT-http_smt-ec2_susecloud_net'.Refreshing service' cloud_update'.Loading repository data...Reading installed packages...Retrieving package telnet-1.2-165.63.x86_64 (1Compact 1) 51.8 KiB (113.3 KiB unpacked) (1 KiB unpacked) / var/cache/zypp/packages/SMT-http_smt-ec2_susecloud_net:SLES12-SP3-Pool/x86_64/telnet-1.2-165.63.x86_64.rpm. [done] download: Done. # ls-lrt / var/cache/zypp/packages/SMT-http_smt-ec2_susecloud_net:SLES12-SP3-Pool/x86_64/total 52murr RWMurray-1 root root 53025 Feb 21 03:17 telnet-1.2-165.63.x86_64.rpm

You can see that we downloaded the telnet package locally using zypper.

How to use zypper to list available package updates

Zypper allows you to browse all available updates for installed packages so that you can plan update activities in advance. Use the list-updates or lu subcommand to display all available updates for the installed package.

The output is deliberately formatted for easy reading. Each column represents the name of the warehouse to which the package belongs, the package name, the installed version, the available updated version, and the schema.

List and install patches in Suse Linux

Use the list-patches or lp subcommand to display all available patches that your Suse Linux system needs to be applied.

The output can be well organized using the appropriate header. You can easily find out and plan your patch updates according to the situation. We can see that 18 of the 37 available patches in our system are security patches that need to be applied with high priority!

You can install all the required patches by issuing the zypper patch command.

How to update a package using zypper

To update a package using zypper, use the update or up subcommand followed by the package name. In the update commands listed above, we know that rsync package updates are available on our server. Let's update it now!

Root@kerneltalks # zypper update rsyncRefreshing service 'SMT-http_smt-ec2_susecloud_net'.Refreshing service' cloud_update'.Loading repository data...Reading installed packages...Resolving package dependencies... The following package is going to be upgraded: rsync 1 package to upgrade.Overall download size: 325.2 KiB. Already cached: 0 B. After the operation, additional 64.0 B will be used.Continue? [y/n/...? Shows all options] (y): yRetrieving package rsync-3.1.0-13.10.1.x86_64 (1Compact 1) 325.2 KiB (625.5 KiB unpacked) Retrieving: rsync-3.1.0-13.10.1.x86_64.rpm. .. [done] Checking for file conflicts:.... ... [done] (1amp 1) Installing: rsync-3.1.0-13.10.1.x86_64.. .. [done] use zypper to find packages on Suse Linux

Don't worry if you're not sure about the full name of the bag. You can use the se or search subcommands that come with zypper and provide a lookup string to find the package.

In the above example, we looked up the lvm string and got the output list as above. You can use the name of the Name field in the zypper install/remove/update command.

Use zypper to check installed package information

You can use zypper to check the details of the installed package. The info or if subcommand lists information about installed packages. It can also display the details of the uninstalled package, in which case the Installed parameter returns the No value.

Root@kerneltalks # zypper info rsyncRefreshing service 'SMT-http_smt-ec2_susecloud_net'.Refreshing service' cloud_update'.Loading repository data...Reading installed packages... Information for package rsync:--Repository: SLES12-SP3-UpdatesName: rsyncVersion: 3.1.0-13.10.1Arch: x86_64Vendor: SUSE LLC Support Level: Level 3Installed Size: 625.5 KiBInstalled: YesStatus: up-to-dateSource package: rsync-3.1.0- 13.10.1.srcSummary: Versatile tool for fast incremental file transferDescription: Rsync is a fast and extraordinarily versatile file copying tool. It can copy locally, to/from another host over any remote shell, or to/from a remote rsync daemon. It offers a large number of options that control every aspect of its behavior and permit very flexible specification of the set of files to be copied. It is famous for its delta-transfer algorithm, which reduces the amount of data sent over the network by sending only the differences between the source files and the existing files in the destination. Rsync is widely used for backups and mirroring and as an improved copy command for everyday use. Use zypper to list warehouses

Use the zypper command to list the warehouse with the lr or repos subcommand.

Root@kerneltalks # zypper lrRefreshing service 'cloud_update'.Repository priorities are without effect. All enabled repositories share the same priority. # | Alias | Name | Enabled | GPG Check | Refresh--- |-- -|- -|-1 | SMT-http_smt-ec2_susecloud_net:SLE-Module-Adv-Systems-Management12-Debuginfo-Pool | SLE-Module-Adv-Systems-Management12-Debuginfo-Pool | No |-|-- 2 | SMT-http_smt-ec2_susecloud_net:SLE-Module-Adv-Systems-Management12-Debuginfo-Updates | SLE-Module-Adv-Systems-Management12-Debuginfo-Updates | No |- -- |-|-3 | SMT-http_smt-ec2_susecloud_net:SLE-Module-Adv-Systems-Management12-Pool | SLE-Module-Adv-Systems-Management12-Pool | Yes | (r) Yes | No 4 | SMT-http_smt-ec2_susecloud_net:SLE-Module-Adv-Systems-Management12-Updates | SLE-Module-Adv-Systems-Management12-Updates | Yes | | (r) Yes | Yes 5 | SMT-http_smt-ec2_susecloud_net:SLE-Module-Containers12-Debuginfo-Pool | SLE-Module-Containers12-Debuginfo-Pool | No |-- |-6 | SMT-http_smt-ec2_susecloud_net:SLE-Module-Containers12-Debuginfo-Updates | SLE-Module-Containers12-Debuginfo-Updates | No | | |-|-|

Here you need to check the enabled column to determine which warehouses are enabled and which are not.

Use zypper to add or remove repositories in Suse Linux

To add a repository you need the URI of the repository or .repo file, otherwise you will encounter the following error.

Root@kerneltalks # zypper addrepo-c SLES12-SP3-UpdatesIf only one argument is used, it must be a URI pointing to a. Repo file.

Using URI, you can add repositories as follows:

Root@kerneltalks # zypper addrepo-c http://smt-ec2.susecloud.net/repo/SUSE/Products/SLE-SDK/12-SP3/x86_64/product?credentials=SMT-http_smt-ec2_susecloud_net SLE-SDK12-SP3-PoolAdding repository 'SLE-SDK12-SP3-Pool'... .... [done] Repository 'SLE-SDK12-SP3-Pool' successfully added URI: http://smt-ec2.susecloud.net/repo/SUSE/Products/SLE-SDK/12-SP3/x86 _ 64/product?credentials=SMT-http_smt-ec2_susecloud_netEnabled: YesGPG Check: YesAutorefresh: NoPriority: 99 (default priority) Repository priorities are without effect. All enabled repositories share the same priority.

In Suse, use the zypper command with the addrepo or ar subcommand to add the repository, followed by URI and you need to provide an alias.

To remove a warehouse in Suse, use the zypper command with the removerepo or rr subcommand.

Root@kerneltalks # zypper removerepo nVidia-Driver-SLE12-SP3Removing repository 'nVidia-Driver-SLE12-SP3'. . [done] Repository 'nVidia-Driver-SLE12-SP3' has been removed. Clear the zypper local cache

Use the zypper clean command to clear the zypper local cache.

Root@kerneltalks # zypper cleanAll repositories have been cleaned up. The above is all the contents of the article "what are the practical zypper commands in linux?" Thank you for reading!
