POSIX.2, X/Open Portability Guide, UNIX systems.
The following are extensions to the POSIX standard:
v The –i option
v The &&and || operators
v The if ... else ... statement
v Identifiers of more than one character or containing characters outside the
POSIX character set
v The print statement
v The sh statement
v The optional parentheses in the return statement
In a doublebyte environment, remember that only numbers and operators from the
POSIX character set can be used. Identifiers can use characters from the current
locale; if you want scripts to be portable, use only characters from the POSIX
character set.
