I moved a directory containing a bunch of symbolic links today, and
the links all broke.  I fixed the links with the following Bash
oneliner (split across lines in this post for clarity):

    $ for FILE in *; do
          if [ -L "${FILE}" ]; then
              TARGET=$(readlink "${FILE}");
              rm -f "${FILE}";
              ln -s "${TARGET/old-dir\//}" "${FILE}";
          fi;
      done

`readlink` prints the value of a symbolic link and
`${TARGET/old-dir\//}` creates the new link target by removing
`old-dir/` from the original target.

You may also find it useful to rename simlinks so that the link
filename matches the target filename:

    $ for x in *; do y=$(basename $(readlink -f "${x}")); mv "${x}" "${y}"; done

This assumes that everything globbed into `x` is a link.  If not, you
can add an `if [ -L "${x}" ]` block like I did in my
target-translation example.
