Copy all files with a certain extension from all subdirectories

--parents is copying the directory structure, so you should get rid of that.

The way you've written this, the find executes, and the output is put onto the command line such that cp can't distinguish between the spaces separating the filenames, and the spaces within the filename. It's better to do something like

$ find . -name \*.xls -exec cp {} newDir \;

in which cp is executed for each filename that find finds, and passed the filename correctly. Here's more info on this technique.

Instead of all the above, you could use zsh and simply type

$ cp **/*.xls target_directory

zsh can expand wildcards to include subdirectories and makes this sort of thing very easy.

From all of the above, I came up with this version. This version also works for me in the mac recovery terminal.

find ./ -name '*.xsl' -exec cp -prv '{}' '/path/to/targetDir/' ';'

It will look in the current directory and recursively in all of the sub directories for files with the xsl extension. It will copy them all to the target directory.

cp flags are:

p - preserve attributes of the file

r - recursive

v - verbose (shows you whats being copied)

I had a similar problem. I solved it using:

find dir_name '*.mp3' -exec cp -vuni '{}' "../dest_dir" ";"

The '{}' and ";" executes the copy on each file.

---

I also had to do this myself. I did it via the --parents argument for cp:

find SOURCEPATH -name filename*.txt -exec cp --parents {} DESTPATH \;

---

find [SOURCEPATH] -type f -name '[PATTERN]' | 
    while read P; do cp --parents "$P" [DEST]; done

you may remove the --parents but there is a risk of collision if multiple files bear the same name.

In 2022 the zsh solution also works in Linux Bash:

cp **/*.extension /dest/dir

works as expected.
