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.
