| # This function scans a directory for symbolic links and replaces the | |
| # leading path prefix of each link target with a new prefix while keeping | |
| # the remainder of the path unchanged. | |
| # | |
| # Only links whose targets match the directory boundary pattern | |
| # OLD_PREFIX/* | |
| # are modified. This prevents accidental matches such as | |
| # /path/foo2 | |
| # when replacing | |
| # /path/foo |
