作为一个具体的例子,我希望能够使用一个未安装的特定工具(例如nslookup),并且能够在下列失败时告诉我需要安装哪个软件包：
apt-get install nslookup E: Unable to locate package nslookup
显然我可以谷歌找到特定包(dnsutils)的答案,但我想知道如何自己找到它.
我知道有两种方法可以做到这一点：
host ~ # apt-file update host ~ # apt-file search nslookup dnsutils: /usr/bin/nslookup dnsutils: /usr/share/man/man1/nslookup.1.gz gajim: /usr/share/gajim/src/common/nslookup.py kaptain: /usr/share/kaptain/nslookup.kaptn kvirc2-data: /usr/share/kvirc2/help/en/nslookup.kvihelp libgnet2.0-0: /usr/share/doc/libgnet2.0-0/examples/dnslookup.c.gz manpages-ja: /usr/share/man/ja/man8/nslookup.8.gz procmail-lib: /usr/share/procmail-lib/pm-janslookup.rc rbot: /usr/share/rbot/plugins/nslookup.rb scrollz: /usr/share/scrollz/help/nslookup zsh: /usr/share/zsh/4.3.4/functions/Completion/Unix/_nslookup zsh: /usr/share/zsh/4.3.4/functions/Misc/nslookup zsh-beta: /usr/share/zsh-beta/functions/Completion/Unix/_nslookup zsh-beta: /usr/share/zsh-beta/functions/Misc/nslookup
和…
host ~ # apt-cache search nslookup host - utility for querying DNS servers dnsutils - Clients provided with BIND
