| 21 | * |
| 22 | * tls -- Trivial recursive ls, for comparing two directories after |
| 23 | * running an rsync. |
| 24 | * |
| 25 | * The problem with using the system's own ls is that some features |
| 26 | * have little quirks that make directories look different when for |
| 27 | * our purposes they're the same -- for example, the BSD braindamage |
| 28 | * about setting the mode on symlinks based on your current umask. |
| 29 | * |
| 30 | * There are some restrictions compared to regular ls: all the names |
| 31 | * on the command line must be directories rather than files; you |
| 32 | * can't give wildcards either. |
| 33 | * |
| 34 | * We need to recurse downwards and show all the interesting |
| 35 | * information and no more. |
| 36 | * |
| 37 | * \todo Use readdir64 if available? |
| 38 | * |
| 39 | * \todo Sort directory entries. Either that, or output file listing |
| 40 | * in such a format that we can just pipe the whole lot through sort. |
