This article is about how Linux uses the command line to uninstall the installation package. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

First, you need to find a list of all installed packages on Linux.

To uninstall the application, you need to use commands specific to the Linux distribution. For example, use the apt command on Debian/Ubuntu. RHEL/ CentOS/Fedora users need to run dnf or yum commands, and so on.

Environment

Ubuntu 18.04 LTS

ArchLinux

Alpine

Fedora

OpenSUSE

Centos 7

Ubuntu/Debian Uninstall package

Use apt to list the installed packages:

Bob@c14f840ed725:~$ sudo apt list-installed

You can also use the dpkg command to find installed packages:

Bob@c14f840ed725:~$ dpkg-l | grep 'ftp'

Let's uninstall the package:

You can use apt or apt-get to uninstall

Bob@c14f840ed725:~$ sudo apt remove vsftpd or bob@c14f840ed725:~$ sudo apt-get remove vsftpdbob@c14f840ed725:~$ sudo apt remove-- purge vsftpd or bob@c14f840ed725:~$ sudo apt-get remove-- purge vsftpd

Add-- purge option, which means that uninstall deletes the configuration file of the package as well.

Verify that the installation package is installed:

Bob@c14f840ed725:~$ apt list-- installed | grep vimWARNING: apt does not have a stable CLI interface. Use with caution in scripts.vim/bionic-updates,bionic-security,now 2 Use with caution in scripts.vim/bionic-updates,bionic-security,now 8.0.1453-1ubuntu1.3 amd64 [installed] vim-common/bionic-updates,bionic-security,now 2 Use with caution in scripts.vim/bionic-updates,bionic-security,now 8.0.1453-1ubuntu1.3 all [installed,automatic] vim-runtime/bionic-updates,bionic-security,now 2 Use with caution in scripts.vim/bionic-updates,bionic-security,now 8.0.1453-1ubuntu1.3 all [installed Automatic] or bob@c14f840ed725:~$ dpkg-l | grep vimii vim 2 automatic 8.0.1453-1ubuntu1.3 amd64 Vi IMproved-enhanced vi editorii vim-common 2 automatic 8.0.1453-1ubuntu1.3 all Vi IMproved-Common filesii vim-runtime 2 race 8.0.1453-1ubuntu1.3 all Vi IMproved-Runtime files

RHEL/CentOS Uninstall package

We can use the previous command to view all installed packages:

[root@qdzabbix ~] # yum list installed or [root@qdzabbix ~] # rpm-qa can also check whether a package is installed: [root@qdzabbix ~] # yum list installed | grep vsftpdvsftpd.x86_64 3.0.2-25.el7 @ base or [root@qdzabbix ~] # rpm-qa | grep vsftpdvsftpd-3.0.2-25.el7.x86_64 [root@qdzabbix ~] #

Delete the installation package:

[root@qdzabbix ~] # yum-y remove vsftpd

Fedora Uninstall package

You can also use yum or dnf Manager on Fedora. It is recommended to use dnf to install and uninstall packages:

# check whether to install vsftpd [root @ 716bc12a2197 ~] # rpm-qa | grep vsftpd# or [root@716bc12a2197 ~] # dnf list installed | grep vsftpd

Uninstall vsftpd:

[root@716bc12a2197 ~] # dnf remove-y vsftpd

Arch Linux Uninstall package

Use the pacman package manager in Arch Linux:

# query whether to install vsftpd [root @ d201bac103e8 /] # pacman-Q vsftpdvsftpd 3.0.3-6 or [root@d201bac103e8 /] # pacman-Q | grep vsftpdvsftpd 3.0.3-6

Uninstall the installation package:

OpenSUSE/SUSE Uninstall package

To manage the installation package using the zypper package Manager in OpenSUSE/SUSE, check to see if vsftpd is installed:

23d5ed5dcfc2:/ # zypper packages-- installed-only | grep vsftpdi+ | OSS Update | vsftpd | 3.0.2-28.1 | x86room64v | OSS Update | vsftpd | 3.0.2-25.1 | x86room64v | OSS | vsftpd | 3 .0.2-23.1 | x86 rpm 64 or 23d5ed5dcfc2:/ # rpm-qa | grep vsftpdvsftpd-3.0.2-28.1.x86_64

Uninstall the installation package:

Alpine Linux Uninstall package

Using the apk package manager in Alpine Linux for package management, check to see if vsfptd is installed:

~ # apk list-I | grep vsftpd

-I lists only installed packages.

Uninstall the installation package:

~ # apk del vsftpd (1amp 3) Purging vsftpd (3.0.3-r6) (2pm 3) Purging libcap (2.27-r0) (3pm 3) Purging linux-pam (1.3.1-r1) Executing busybox-1.31.1-r9.triggerOK: 6 MiB in 14 packages
