Simultaneously moving and renaming files in Red Hat

Question

I'm running Red Hat Release 6.5 (Santiago). The problem I'm facing is that I have a bunch of files in the following directory structure:

temp2
├── ABC
│   └── temp2
│       └── temp2.txt
└── DEF
    └── temp2
        └── temp2.txt

I'm trying to change it to the structure as below, but have no idea how to get it done.

temp2
├── ABC.txt
└── DEF.txt

Any help would be greatly appreciated!

Answer 1

You need to create a small script file to do your rename/move: call it rnmv, say, and put the following command into it:

f="${1#./}"; echo mv "$f" "${f%%/*}.${f##*.}"

Don't forget to chmod +x rnmv. Then go to the root directory and call rnmv from a find command:

cd {wherever temp2 root is}
find . -name "temp2.txt" -exec rnmv "{}" \;

When you are happy that the correct mv commands are being created, remove the echo from rnmv and your rename/move will be done.

One final task is to remove the empty subdirectories:

find . -name temp2 -exec rmdir "{}" \;

This is safe, as rmdir will not remove a directory with files in it. Depending on the order of finding the directories, you may need to repeat the command for structures like ABC/temp2/temp2, as the temp2 will not be empty until the second is deleted.

Note that if ABC, say, has more that one temp2.txt file in its subdirectories, each mv command will overwrite the previous ABC.txt, and only the last found will be left afterwards.

Answer 2

mv /temp2/ABC/temp2/temp2.txt /temp2/ABC.txt
mv /temp2/DEF/temp2/temp2.txt /temp2/DEF.txt

Depending on where the high-level temp2 directory is - I cannot tell from your example.
