UNIX® Commands & Utilities Interface Table

The following table lists all the Commands and Utilities described in the Single UNIX Specification, and indicates what other specifications support the interfaces.

The following conventions are used in columns 2 through 6:

m

Indicates that the interface is defined as mandatory.

d

Indicates that the interface is part of the Development option.

f

Indicates that the interface is part of the Fortran option.

l

Indicates that the interface is part of the Legacy option.

o

Indicates that the interface is optional.

.

Indicates that the interface is not specified.

It should be noted that while another specification may support the interface, some of the interface semantics may have changed with its evolution and standardisation. A developer should not assume that because the interface appears in other specifications, it will behave exactly as described in the Single UNIX Specification.
