ACL Utilities ACL Utilities Overview
• You can specify integer input values using a standard decimal number, a hexadecimal
value (first two characters are 0x), or an octal value (the first character is a zero and the
second character is not an x).
5.2.4 Output Conventions
The ACL Management Utilities have the following output conventions:
• Many utilities support the -stdout <output_spec> argument which specifies the output
stream written to stdout. Each output field in the string is identified by a unique keyword
[%field_name or %(field_name)] that you can specify to display the field, or omit to skip
the field.
• All error and help messages are written to stderr.
• All utilities use exit status codes to indicate success or failure. See “Exit Status” on page
5-7 for detailed information on exit status codes.
5.2.5 Arguments
The arguments supported by more than one utility are described below. For other arguments,
consult each utility’s manual page.
-help [
help_type ]
Displays help on stderr and invalidates all other options, cancelling any other actions. The
optional help_type specification indicates the kind of help to supply:
• stdout - lists the keywords that are valid for the -stdout <output_spec> argument.
• revision - displays the ACL Management utilities release number.
• v_revision - displays the utilities revision number, release date, and engineering release
character.
When -help is specified without the help_type argument, it displays information on the utility
usage line.
-stdout <
output_spec>
The -stdout <output_spec> argument specifies the output stream written to stdout. It is
required for all ACL Management Utilities that produce an output, unless you use the -help
argument.
The -stdout <output_spec> argument allows you to specify the following:
