On this man page, ksh(1) commands that are preceded by one or two * (asterisks) are treated specially in the following ways:
.
- Variable assignment lists preceding the command remain in effect when the command completes.
.- I/O redirections are processed after variable assignments.
.- Errors cause a script that contains them to abort.
.- Words, following a command preceded by ** that are in the format of a variable assignment, are expanded with the same rules as a variable assignment. This means that tilde substitution is performed after the = sign and word splitting and file name generation are not performed.
