/ 57 $ mkdir -p hello-sh/hello-sh-1.0; cd hello-sh/hello-sh-1.0 $ cat > hello <cd .. $ tar -cvzf hello-sh-1.0.tar.gz hello-sh-1 錯誤，即便是有一點 不恰當也不行，因爲在別人的系統上解包這些文件時，可能他們的工具並不忽略這些反常的現象， 於是就會出現問題。在你的終端屏幕上，應該看到如下的情形。 $ mkdir ~/gentoo ; cd ~/gentoo $ wget http://www.example.org/gentoo-0.9.12.tar.gz $ tar xvzf gentoo-0.9.12.tar.gz $ ls -F 軟件包，你可以爲它創建一個初始的外來 Debian 軟件包，通過如下方法調用 dh_make 命令： $ cd ~/gentoo $ wget http://example.org/gentoo-0.9.12.tar.gz $ tar -xvzf gentoo-0.9.12.tar.gz $ cd gentoo-0.9.12 $ dh_make -f ../gentoo-0.9.12.tar.gz

創建並進入一個工作目錄: mkdir /tmp/debian-tutorial ; cd /tmp/debian-tutorial 3 把 dash 原始碼套件下載下來 apt-get source dash (務必確保 deb-src 已加入 /etc/apt/sources.list) 4 構建套件 cd dash-* debuild -us -uc (-us -uc 代表不使用GPG來簽署套件) simgrid_3.6.orig.tar.gz) ▶ 解開此 tar 檔 ▶ 將目錄改名為 - (範例: simgrid-3.6) ▶ cd - && dh_make (來自 dh-make 套件) ▶ 對於特定套件, 有除了 dh_make 以外的方法, 舉例為: dh-make-perl tar.gz ▶ mv gnujump-1.0.8.tar.gz gnujump_1.0.8.orig.tar.gz ▶ tar xf gnujump_1.0.8.orig.tar.gz ▶ cd gnujump-1.0.8/ ▶ dh_make -f ../gnujump-1.0.8.tar.gz ▶ 套件種類: 單一二進制 (for now) gnujump -1.0.8$ ls debian/
