| 2 | Busybox POSIX conformance table |
| 3 | |
| 4 | See POSIX documentation (1003.1-2008) here: |
| 5 | http://www.opengroup.org/onlinepubs/9699919799/ |
| 6 | And the complete list of all utilities that POSIX covers: |
| 7 | http://www.opengroup.org/onlinepubs/9699919799/utilities/utilities.html |
| 8 | |
| 9 | This listing is a work in progress, and currently only covers |
| 10 | tool options (not operands, enviroment variables, return codes, etc..). |
| 11 | For each option it is set if it (a) exists and (b) compliant to POSIX 2008. |
| 12 | Some options exist but there is no value in the 'compliant' column: that |
| 13 | means no one has yet bothered to make sure that the option does what it is |
| 14 | required to do. |
