12.1.8. zenity 的 shell 脚本案例

下面是一个简单的脚本，它通过 dvdisaster(1) 创建了带有 RS02 补充数据的 ISO 映像。

  1. #!/bin/sh -e
  2. # gmkrs02 : Copyright (C) 2007 Osamu Aoki <osamu@debian.org>, Public Domain
  3. #set -x
  4. error_exit()

  12. if [ $# != 0 ] && [ -d "$1" ]; then
  13.   DATA_SRC="$1"
  14. else

  17.     --title="Select the directory tree root to create ISO image") \

  43. # EOF

你可能想要在桌面创建一个启动器，其中的命令设置为类似 “/usr/local/bin/gmkrs02 %d” 的形式。
