1.6. Solaris: Standard Compliant Programs
There are a number of different standards that specify the behavior
of portable programs in a Unix-like environment.
POSIX 1003.2 and XPG4 are two of the more widely known ones.
Where the behavior specified by a standard differs from the
historical behavior provided by a command,
Solaris provides a different version of the command
in /usr/xpg4/bin.
These commands are listed here, but not otherwise covered in
this book, as most users typically do not have /usr/xpg4/bin
in their search paths.
The manual entries for each command discuss the differences
between the /usr/bin version and
the /usr/xpg4/bin version.
