How to bulk replace a symlink?

Question

bash

find /etc/nginx/bx -type l -name '*ks10.ks10.ru*' | sed -e 'p;s/ks10.ks10.ru/ks11.ks11.ru/g' | xargs -n2 mv

Renaming the file itself works, but not the links in it, so you need to replace the link itself, how to do this?

Answer 1

find /etc/nginx/bx -type l -name '*ks10.ks10.ru*' | xargs ls -l | awk '{print $11, $9}' | sed -e 's/ks10.ks10.ru/ks11.ks11.ru/g' | xargs -n2 ln -s

At the same time, old symlinks are not deleted, only new ones are created; but it will not be difficult for you to remove the old ones.
And the solution is not universal - it should work for symlinks with absolute paths, but not with relative ones (it’s more difficult there, you have to parse the paths and separately take into account two points in them, in general, I’m lazy). But you seem to have absolute paths in symlinks.
Upd. sergey kuzmin in the comments suggested a wonderful readlink command, which, with the -f option, should immediately give out the full path via the symlink, so that universality can be achieved without complication.

man rename
