这个脚本求大神帮我弄一下哈

[就呆在云上]

这个脚本是linux上面做一个文件系统的，我在UML官网下的，有问题如下：

[root@zhoutianzuo azuo]# bash install_fs.sh 
Filesystem already created
Filesystem already mounted
going to fetch
Usage: grep [OPTION]... PATTERN [FILE]...
Try `grep --help' for more information.
Usage: grep [OPTION]... PATTERN [FILE]...
Try `grep --help' for more information.
Usage: grep [OPTION]... PATTERN [FILE]...
Try `grep --help' for more information.

谁帮我修改一下哈，要求功能ok，谢谢了。

脚本有点长，我就发了博客，请到博客看看哈，谢谢了：

没试, 简单看到20行的grep调用的$1是42行传入的，传入时候追加了一个-，你在20行里用"$1"应该就好了。

我把42行的'－'去掉了，还是不行哈，依旧是之前的错误提示。

脚本这个懂的不多，再帮我下哈，谢谢了

现在我打开debug之后，打印是这样的：


1、去掉42行的－，打印如下
going to fetch
grep i386 packages.i386 | grep | wc -l
Usage: grep [OPTION]... PATTERN [FILE]...
Try `grep --help' for more information.
No RPMs found for i386 -
grep i686 packages.i386 | grep | wc -l
Usage: grep [OPTION]... PATTERN [FILE]...
Try `grep --help' for more information.
No RPMs found for i686 -
grep noarch packages.i386 | grep | wc -l
Usage: grep [OPTION]... PATTERN [FILE]...
Try `grep --help' for more information.

Usage: grep [OPTION]... PATTERN [FILE]...
Try `grep --help' for more information.

grep noarch packages.i386 | grep | wc -l

No RPM package found for

2、补上42行的－号
[root@zhoutianzuo my_fs]# vim install_fs.sh
[root@zhoutianzuo my_fs]# bash install_fs.sh
Filesystem already created

going to fetch
grep - packages.i386 | grep i386 | wc -l

[root@zhoutianzuo my_fs]#

从报错来看 是GREP的语句格式出现了问题 42行如楼上所说 $1后的 -位置有的问题
No RPMs found for - - i686 这个是脚本的执行返回 属于正常

估计是一些参数或者定位符的位置 多个空格少个空格导致
