如何在现有文件夹树中（在每个现有文件夹中）递归创建文件夹？

Question

I'm trying to create a new folder in an existing tree with :

find /home/a/Desktop/MyCycles/DavidSilver -type d -exec sh -c '(cd {} && mkdir bin)' ';'

In Ubuntu , but I get an infinite loop of

mkdir: cannot create directory ‘bin’: File exists

Which BTW is not true , since the folder doesn't exist in each of the subfolders of /home/a/Desktop/MyCycles/DavidSilver .

Any idea how can I fix this ?

Thanks

Assuming GNU find(1) :

find /home/a/Desktop/MyCycles/DavidSilver -type d -printf '%p/bin\0' | xargs -0 mkdir

Withtout GNU find(1) , but assuming directory names don't contain newlines:

find /home/a/Desktop/MyCycles/DavidSilver -type d | \
    sed 's!$!/bin!' | \
    xargs mkdir
