如何在Linux中递归运行mv命令

Question

My environment: Bash 3.5 LinuxRedhat

I'm using the following code to rename all of my files in a single directory.

for file in *.* ; do mv "$file" "Add_$file" ; done

Now, I want to rename my file recursively.And I don't know how to do.

The first ideas with find don't work, because {} returns ./ with the command:

find . -type f -name "*.*" -execdir mv {} Add_{} ";"

We need something, which removes the ./ in front but works in subdirectories too.

echo 'f=$(basename "$1"); mv "$f" Add_"$f";' > adhoc.sh
chmod a+x adhoc.sh
find . -type f -name "*.*" -execdir $PWD/adhoc.sh "{}" ";"

At least this works for gnu-find . Other finds might not have an -execdir command.

Thanks for skyking for pointing my error out.

For Linux, you might find a version of 'rename' in the repository, but normally it has to be installed and isn't part of the standard installation. If you often rename with the commandline, it is worth the effort. With rename , you specify a regex substitute command and can test it first:

find . -type f -exec rename -n "s/(.*)/Add_\1/" {} ";"
