我写的一个自动mount各类分区的脚本（能为vfat分区加上iocharset参数）

home_king

最初由 ccwufu 发表
在knoppix , morphix , gnoppix 等live cd 中， 已经有了auto-buildfstab
可以实现类似功能（不会根基$LANG or $LC_CTYPE来处理不同的语言环境）

因为我正在定制morphix(不想定制base-module, auto-buildfstab 在其中）
想在auto-buildfstab生成的fstab基础上，给vfat , ntfs 分区加上iocharset / codepage 选项，
能否帮忙写一个script : fstab-convert.sh
"fstab-convert.sh  fstab.org  fstasb.cn"

请指教！谢谢！

请参考ibox livecd的domount代码。

看来我能写出这样子的代码还得拼命学几天啊，呵呵

huanglao

那位高手能讲解以下其中的 代码，能让新手看明白亚 !!
多谢了！！！！！！！！

MOUNTOPTIONS="iocharset=gb2312,codepage=936"
对ntfs也好用吗？
怎么在网上，很多人提到对ntfs用utf8比较好。

食古不化

无论utf8还是cp936,我在ntfs下的目录或文件总有只见名称无法打开的。报错说没有这个文件或目录。

ccwufu

ntfs 用utf8
在rox-filer下中文显示很好，也可以进入中文目录
(基本没有漏字，LANG=zh_CN.GBK)

谢谢ccwufu指点，我常用krusader。试验了fox和nautilus在utf8下挂载可以显示。
