尽管在图形包管理器的帮助下,包管理已经变得更容易,但有些用户始终更喜欢命令行方式。
有不同的命令可以在不同的Linux中查找包版本。
今天,在本教程中,我们将看到如何在一些流行的Linux发行版中找到一种包装版本,例如Arch Linux及其衍生品,Debian及其衍生品,Rhel及其衍生品。
在基于Arch的系统中查找包版本
要查找Arch Linux中的已安装包(例如,VLC)版本及其衍生物(如Manjaro Linux),请运行以下命令:
$pacman -Q vlc
示例输出:
vlc 2.2.4-3
如上所述,VLC包的已安装版本为2.2.4-3.
要显示包的广泛细节,请运行:
$pacman -Qi vlc
示例输出:
Name : vlc Version : 2.2.4-3 Description : A multi-platform MPEG, VCD/DVD, and DivX player Architecture : x86_64 URL : http://www.videolan.org/vlc/ Licenses : LGPL2.1 GPL2 Groups : None Provides : None Depends On : a52dec libdvbpsi libxpm libdca libproxy sdl_image libdvdnav libtiger lua libmatroska zvbi taglib libmpcdec ffmpeg2.8 faad2 libupnp libshout libmad libmpeg2 xcb-util-keysyms libtar libxinerama Optional Deps : avahi: for service discovery using bonjour protocol [installed] libnotify: for notification plugin [installed] gtk2: for notify plugin [installed] [...] lua-socket: for http interface qt4: for the GUI [installed] Required By : None Optional For : smtube Conflicts With : vlc-plugin Replaces : vlc-plugin Installed Size : 53.28 MiB Packager : Antonio Rojas <Hyman@theitroad> Build Date : Sun 24 May 2015 03:12:59 PM IST Install Date : Fri 05 Aug 2015 11:22:54 AM IST Install Reason : Explicitly installed Install Script : No Validated By : Signature

在基于Deb的系统中查找包版本
在Debian,Ubuntu及其衍生品如Linux Mint,Mexhileary OS,我们可以找到已安装的包,例如Apache WebServer,使用命令版本:
$dpkg -s apache2 | grep -i version
示例输出:
Version: 2.4.18-2ubuntu3.1
要显示已安装包的广泛信息,请运行:
$dpkg -s apache2
示例输出:
Package: apache2 Status: install ok installed Priority: optional Section: httpd Installed-Size: 488 Maintainer: Ubuntu Developers <Hyman@theitroad> Architecture: amd64 Version: 2.4.18-2ubuntu3.1 Replaces: apache2.2-bin, apache2.2-common Provides: httpd, httpd-cgi Depends: lsb-base, procps, perl, mime-support, apache2-bin (= 2.4.18-2ubuntu3.1), apache2-utils (>= 2.4), apache2-data (= 2.4.18-2ubuntu3.1) Pre-Depends: dpkg (>= 1.17.14) Recommends: ssl-cert Suggests: www-browser, apache2-doc, apache2-suexec-pristine | apache2-suexec-custom, ufw Conflicts: apache2.2-bin, apache2.2-common Conffiles: /etc/apache2/apache2.conf da32fcc6a783acaebf0d74c17c726bf7 /etc/default/apache-htcacheclean ae8721a0bc5b4e2ef7a5258b1e9db5c5 [..] /etc/logrotate.d/apache2 7322a4f050c1e2454249695236a3472c /etc/ufw/applications.d/apache2-utils.ufw.profile f8d4fd920e598ceb4379613c6261f6af Description: Apache HTTP Server The Apache HTTP Server Project's goal is to build a secure, efficient and extensible HTTP server as standards-compliant open source software. The result has long been the number one web server on the Internet. . Installing this package results in a full installation, including the configuration files, init scripts and support scripts. Homepage: http://httpd.apache.org/ Original-Maintainer: Debian Apache Maintainers <Hyman@theitroad>
此外,我们可以使用命令找到包版本:
$apt-show-versions apache2
示例输出:
apache2:amd64/xenial-security 2.4.18-2ubuntu3.1 uptodate apache2:i386 not installed
如上所述,我已安装Apache2 64位版本,其版本为2.4.18.
如果未安装"APT-Show-Versions"程序,则可以使用命令安装它:
$sudo apt install apt-show-versions
在基于RPM的系统中查找包版本
要在基于RPM的分布中查找已安装的包(例如,EG.HTTPD)的版本,如RPM,CentOS,Fedora,Scientific Linux和OpenSUSE等,运行:
$rpm -qi httpd
示例输出:
Name : httpd Version : 2.4.6 Release : 40.el7.centos.4 Architecture: x86_64 Install Date: Thu 11 Aug 2015 08:08:45 PM IST Group : System Environment/Daemons Size : 9806117 License : ASL 2.0 Signature : RSA/SHA256, Mon 18 May 2015 09:35:16 PM IST, Key ID 24c6a8a7f4a80eb5 Source RPM : httpd-2.4.6-40.el7.centos.4.src.rpm Build Date : Mon 18 May 2015 09:02:11 PM IST Build Host : worker1.bsys.centos.org Relocations : (not relocatable) Packager : CentOS BuildSystem <http://bugs.centos.org> Vendor : CentOS URL : http://httpd.apache.org/ Summary : Apache HTTP Server Description : The Apache HTTP Server is a powerful, efficient, and extensible web server.
上面的命令显示已安装的包版本,构建日期,许可证,描述等。
在输出中看到,Httpd软件包版本为2.4.6.
