Linux 查找和复制文件

Find and copy files

提问by shantanuo

Why does the following does not copy the files to the destination folder?

为什么下面没有将文件复制到目标文件夹？

# find /home/shantanu/processed/ -name '*2011*.xml' -exec cp /home/shantanu/tosend {} \;

cp: omitting directory `/home/shantanu/tosend'
cp: omitting directory `/home/shantanu/tosend'
cp: omitting directory `/home/shantanu/tosend'

If your intent is to copy the found files into /home/shantanu/tosend you have the order of the arguments to cp reversed:

如果您的目的是将找到的文件复制到 /home/shantanu/tosend 中，则 cp 的参数顺序颠倒了：

find /home/shantanu/processed/ -name '*2011*.xml' -exec cp "{}" /home/shantanu/tosend  \;

Note: find command use {}as placeholder for matched file

注意：find 命令使用{}作为匹配文件的占位符

You need to use cp -t /home/shantanu/tosendin order to tell it that the argument is the target directory and not a source. You can then change it to -exec ... +in order to get cpto copy as many files as possible at once.

您需要使用cp -t /home/shantanu/tosend来告诉它参数是目标目录而不是源。然后，您可以将其更改为-exec ... +，以便cp一次复制尽可能多的文件。

Actually, in two ways you can process findcommand output in copycommand

实际上，可以通过两种方式find在copy命令中处理命令输出

1. If findcommand's output doesn't contain any space i.e if file name doesn't contain space in it then you can use below mentioned command:

   Syntax: find <Path> <Conditions> | xargs cp -t <copy file path>

   Example: find -mtime -1 -type f | xargs cp -t inner/

2. But most of the time our production data files might contain space in it. So most of time below mentioned command is safer:

   Syntax: find <path> <condition> -exec cp '{}' <copy path> \;

   Example find -mtime -1 -type f -exec cp '{}' inner/ \;

1. 如果find命令的输出不包含任何空格，即如果文件名中不包含空格，那么您可以使用下面提到的命令：

   句法： find <Path> <Conditions> | xargs cp -t <copy file path>

   例子： find -mtime -1 -type f | xargs cp -t inner/

2. 但大多数情况下，我们的生产数据文件中可能包含空间。所以大部分时间下面提到的命令更安全：

   句法： find <path> <condition> -exec cp '{}' <copy path> \;

   例子 find -mtime -1 -type f -exec cp '{}' inner/ \;

In the second example, last part i.e semi-colon is also considered as part of findcommand, that should be escaped before press the enter button. Otherwise you will get an error something like this

在第二个例子中，最后一部分，即分号也被视为find命令的一部分，应该在按下回车按钮之前转义。否则你会得到类似这样的错误

find: missing argument to `-exec'

In your case, copy command syntax is wrongin order to copy find file into /home/shantanu/tosend. The following command will work:

在你的情况下，复制命令语法是错误的，以便找到文件复制到/home/shantanu/tosend。以下命令将起作用：

find /home/shantanu/processed/ -name '*2011*.xml' -exec cp  {} /home/shantanu/tosend \;

The reason for that error is that you are trying to copy a folder which requires -r option also to cp Thanks

该错误的原因是您正在尝试将需要 -r 选项的文件夹复制到 cp 谢谢
