| 35 | usage: namei pathname [pathname ... ] | |
| 36 | ||
| 37 | This program reads it's arguments as pathnames to any type | |
| 38 | of Unix file (symlinks, files, directories, and so forth). | |
| 39 | The program then follows each pathname until a terminal | |
| 40 | point is found (a file, directory, char device, etc). | |
| 41 | If it finds a symbolic link, we show the link, and start | |
| 42 | following it, indenting the output to show the context. | |
| 43 | ||
| 44 | This program is useful for finding a "too many levels of | |
| 45 | symbolic links" problems. | |
| 46 | ||
| 47 | For each line output, the program puts a file type first: | |
| 48 | ||
| 49 | f: = the pathname we are currently trying to resolve | |
| 50 | d = directory | |
| 51 | D = directory that is a mount point | |
| 52 | l = symbolic link (both the link and it's contents are output) | |
| 53 | s = socket | |
| 54 | b = block device | |
| 55 | c = character device | |
| 56 | - = regular file | |
| 57 | ? = an error of some kind | |
| 58 | ||
| 59 | The program prints an informative messages when we exceed | |
| 60 | the maximum number of symbolic links this system can have. | |
| 61 | ||
| 62 | The program exits with a 1 status ONLY if it finds it cannot | |
| 63 | chdir to /, or if it encounters an unknown file type. | |
