Linux application - find files to copy [case]
This article shares a Linux application case with you. The requirements are as follows:
/aContents under the directory
/a/login1.txt
/a/login2.txt
/a/login3.txt
/a/login4.txt
/a/b/login5.txt
/a/b/login6.txt
We find all the file names starting with login under the /a directory and copy them to the /login directory.
This problem can be solved well by using the find command, which can be used in two ways.
First, use the -exec option of the find command to execute the corresponding command
$ find /a –name login* -exec cp {} /b \;
{}Indicates the content found by find
-execIt is the beginning of the extra action of the find command; ; indicates the end of the extra action. The part between -exec and ; is the command executed by the extra action.
Second, using pipelines | and xargscommands
$ find /a –name login* | xargs cp –t /b
xargs reads the result of find as the input data of cp. It should be noted that the cp command must be added with the -t option. Because the directory followed by the -t option is the target directory. If -t is not added, -b will be considered as the source directory, and the file read by xargs becomes the target directory. This will report an error.
The above two methods can solve our needs. I hope this article will be helpful to you.
