rsync-复制具有相同名称的文件

Question

I have some different files with the same name and I want to copy all of them to the destination which has a flat structure (no directories, just files), is there any way to append some text onto one of the file names so that both can be copied.

Need to use rsync because there are some files that I need to exclude from the copy.

For example: dir1/file1.txt dir1/dir2/file1.txt both get copied, and in the destination there is: file1.txt file1.txt.txt

Answer 1

typically, when I want to do some complex name-mungling, I just write the list of files (with find dir1 >listfiles ) and fix it with a text editor.

for example, s/^.*\\/([^\\/]+)$/cp \\0 destination/\\1/ converts a file like

dir1/file1.txt
dir1/dir2/file1.txt

to a script like:

cp dir1/file1.txt destination/file1.txt
cp dir1/dir2/file1.txt destination/file1.txt

then you could do something like cut -f 3 <listfiles | sort | uniq -d cut -f 3 <listfiles | sort | uniq -d cut -f 3 <listfiles | sort | uniq -d to find those with the same destination filename. then go back to the editor and fix those lines.

After a few minutes you get a full script for exactly the copy you want, without surprises because you can see each command and apply the best fix for each case.

Answer 2

As far as i know there is no default option in rsync to do that. But i guess that since you are copying files with the same name but from different directories, you are using multiple rsync commands.

So, this gives you two options:

Create folders..

rsync -av /home/user1/file1 /media/foo/user1/file1
rsync -av /home/user2/file1 /media/foo/user2/file1
etc..

or rename the files with an id

rsync -av /home/user1/file1 /media/foo/parent_dir-file1
rsync -av /home/user2file1 /media/foo/parent_dir-file1
etc..

If you want to use the second solution you can build a simple script. As you are using rsync i suppose that you know the basics on GNU-Linux, so a simple bash script would be enough!

A basic ID is to get the parent folder name and add it as variable to the path of the rsync command. ( it won't always work )

IF you want to be sure of a good id you can for example set a counter and increment like

 file1-1
 file1-2
 file1-3

But you will loose the track of its absolute path.

All the solutions can work, its up to you to choice the one that feed your needs!
