Linux command – yum whatprovides

有時候某一個程式沒有安裝 ,我怎麼知道他是放在哪一個套件裡的, #apt-get install command 本身就會幫忙搜尋,不用特別的方式.

• APT

  比如我要找 #ifconfig , #apt-get 會提示你的工具是放在哪一個套件裡.

  root@benjr:~# apt-cache search ifconfig
  iproute2 - networking and traffic control tools
  net-tools - The NET-3 networking toolkit
  gnome-nettool - network information tool for GNOME
  inetutils-tools - base networking utilities (experimental package)
  libnet-ifconfig-wrapper-perl - multiplatform Perl wrapper for ifconfig
  moreutils - additional Unix utilities
  wmifinfo - Dockapp that shows information for all interfaces
  

  或是透過 apt-file 去找,會有比較多的資訊可供查詢.不過 #apt-file 非預設安裝,需要額外安裝.安裝後的第一步就是先更新資料庫.

  root@benjr:~# apt-get install apt-file
  root@benjr:~# apt-file update
  root@benjr:~# apt-file find ifconfig |grep -i /sbin/
  linux-cloud-tools-common: /usr/sbin/hv_set_ifconfig
  linux-lts-vivid-cloud-tools-common: /usr/sbin/hv_set_ifconfig
  net-tools: /sbin/ifconfig
  python-ethtool: /usr/sbin/pifconfig
  

  安裝與 #ifconfig 相關的套件 net-tools – The NET-3 networking toolkit 後,一樣可以透過 #apt-file 檢查 net-tools – The NET-3 networking toolkit 套件內容為何.

  root@benjr:~# apt-file list net-tools |grep -i ifconfig
  net-tools: /sbin/ifconfig
  net-tools: /usr/share/man/de/man8/ifconfig.8.gz
  net-tools: /usr/share/man/fr/man8/ifconfig.8.gz
  net-tools: /usr/share/man/man8/ifconfig.8.gz
  net-tools: /usr/share/man/pt_BR/man8/ifconfig.8.gz
  

• yum

  但是 yum 就沒有提供這一項功能了,我們可以透過 #yum whatprovides

  [root@benjr ~]# yum install ifconfig
  Loaded plugins: fastestmirror
  Loading mirror speeds from cached hostfile
   * base: mirror01.idc.hinet.net
   * extras: ftp.twaren.net
   * updates: ftp.twaren.net
  No package ifconfig available.
  Error: Nothing to do
  

  一樣是找 #ifconfig ,這結果比 #apt-get 提供的還要清楚,一看就知道是 net-tools (Filename : /sbin/ifconfig) 套件提供的.

  [root@benjr ~]# yum whatprovides "*ifconfig"
  Loaded plugins: fastestmirror
  Loading mirror speeds from cached hostfile
   * base: mirror01.idc.hinet.net
   * extras: ftp.twaren.net
   * updates: ftp.twaren.net
