Table 3-1 lists the Commands and Utilities required to be present on a conforming system. These commands and utilities shall behave as described in the relevant underlying specification, with the following exceptions:
If any operand (except one which follows --) starts with a hyphen, the behavior is unspecified.
Rationale (Informative) | |
---|---|
Applications should place options before operands, or use
--, as needed. This text is needed because GNU option parsing
differs from POSIX. For example, ls . -a in GNU
ls means to list the current directory, showing all
files (that is, "." is an operand and -a is an
option). In POSIX, "." and -a are both operands,
and the command means to list the current directory, and also the file
named -a. Suggesting that applications rely on the
setting of the |
The behavior of the interfaces described in this section is specified by the following standards.
