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