Question

我刚才认为,我找到了解决办法,因为指挥官在我的试验台工作。

grep -H -e  author="[^"].*  *.xml | cut -d: -f1 | xargs -I  {}  mv {} mydir/.

But using the command in the non-test-direcory the command did not work: This is the error message:

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

甚至没有这样做:

$ grep -H author *.xml

或

$ grep -H  author  *.xml

(错误信息)

I suspect it has some relation to the file names or the amount of files. I have almost 3000 files in the non-test-directory and only 20 in my test directory. In both directories almost all file names contain spaces and " - ".

I m using Cygwin.
I am not allowed to change the filenames

(日期):

grep -HlZ  author="[^"].*  -- *.xml | xargs -0 -I {} mv -- {} mydir/

EXPLANATION (updated)

In your "real" directory you have a file with name starting with -O. Your shell expands the file list *.xml and grep takes your - starting filename as an option (not valid). Same thing happens with mv. As explained in the Common options section of info coreutils, you can use -- to delimit the option list. What comes after -- is considered as an operand, not an option.
采用<代码>-l(下限L)办法,grep只使用配对文档的名称,因此,你无需使用<代码>cut。
为了正确处理每一个小标题,你必须使用<代码>-Z>,载于grep/code>和-0,载于xargs。

无需使用<代码>-e,因为您的模式不始于<代码>-。

希望这将有助于!
