Move files that are 30 minutes old
提问by saurabh
I work on a server system that does not allow me to store files more than 50 gigabytes. My application takes 20 minutes to generate a file. Is there any way whereby I can move all the files that are more than 30 minutes old from source to destination? I tried rsync:
我在不允许我存储超过 50 GB 的文件的服务器系统上工作。我的应用程序需要 20 分钟来生成一个文件。有什么方法可以将超过 30 分钟的所有文件从源移动到目标吗？我试过rsync：
rsync -avP source/folder/ user@destiantionIp:dest/folder
but this does not remove the files from my server and hence the storage limit fails.
但这不会从我的服务器中删除文件，因此存储限制失败。
Secondly, if I use the mvcommand, the files that are still getting generated also move to the destination folder and the program fails.
其次，如果我使用该mv命令，仍在生成的文件也会移动到目标文件夹并且程序失败。

You can use findalong with -execfor this:-
您可以find与-exec此一起使用：-
Replace /sourcedirectoryand /destination/directory/with the source and target paths as you need.
根据需要替换/sourcedirectory和/destination/directory/源路径和目标路径。
find /sourcedirectory -maxdepth 1 -mmin -30 -type f -exec mv "{}" /destination/directory/ \;
What basically the command does is, it tries to find files in the current folder -maxdepth 1that were last modified 30 mins ago -mmin -30and move them to the target directory specified. If you want to use the time the file was last accessed use -amin -30.
该命令的基本作用是，它尝试在当前文件夹-maxdepth 1中查找30 分钟前最后修改的文件-mmin -30并将它们移动到指定的目标目录。如果要使用上次访问文件的时间，请使用-amin -30.
Or if you want to find files modified within a range you can use something like -mmin 30 -mmin -35which will get you the files modified more than 30 but less than 35 minutes ago.
或者，如果您想查找在某个范围内修改的文件，您可以使用类似的方法-mmin 30 -mmin -35，这将使您修改超过 30 分钟但不到 35 分钟前的文件。
References from the manpage:-
man页面参考：-
-amin n
File was last accessed n minutes ago.
-atime n
File was last accessed n*24 hours ago. When find figures out how many 24-hour periods ago the file was last accessed, any fractional part is ignored, so to match -atime
+1, a file has to have been accessed at least two days ago.
-mmin n
File's data was last modified n minutes ago.
-mtime n
File's data was last modified n*24 hours ago. See the comments for -atime to understand how rounding affects the interpretation of file modification times.
