How to batch append subdirectory to link target in bash

I have a directory under my control with a lot of symbolic links to sub-directories in another directory not under my control. The "format" has recently changed, and I would like to update all my symbolic links to append "new" to the link target.

Example of the current situation:

u -> /catalog/uvw

v -> /catalog/uvw

x -> /catalog/xyz

y -> /catalog/xyz

...

How can I batch-append a subdirectory to each link target, so that the new links have the following targets?

u -> /catalog/uvw/new

v -> /catalog/uvw/new

x -> /catalog/xyz/new

y -> /catalog/xyz/new

...

Solution

Please try the following:

find . -type l -maxdepth 1 -print0 | while IFS= read -r -d "" link; do
    target="$(readlink "$link")"
    ln -nfs "$target/new" "$link"
done

Hope this helps.
