gawk and /usr/xpg4/bin/awk on Solaris functions correctly though (nawk does not, but it is not POSIX compliant so I would not expect it to).
Mac OS X picks up most of its utilities from BSD, and most of the OS X utilities do adhere to the POSIX standards requirements even in places where BSD utilities sometimes fail. The
awk utility, however, fails on at least two counts:
- length() should count characters; but instead it counts bytes, and
- awk -v variable=value 'script' and awk -vvariable=value 'script' should be treated exactly the same, but the 1st form works and the 2nd form gives a syntax error.
At least both
bash and
ksh on OS X correctly count characters (not bytes) with
${#variable}.

audit(4) Kernel Interfaces Manual audit(4)
NAME
audit - audit trail format and other information for auditing
DESCRIPTION
Audit records are generated when users make security-relevant system calls, as well as by self-auditing processes that call (see aud-
write(2)). Access to the auditing system is restricted to super-user.
Each audit record consists of an audit record header and a record body. The record header is comprised of sequence number, process ID,
event type, and record body length. The sequence number gives relative order of all records; the process ID belongs to the process being
audited; the event type is a field identifying the type of audited activity; the length is the record body length expressed in bytes.
The record body is the variable-length component of an audit record containing more information about the audited activity. For records
generated by system calls, the body contains the time the audited event completes in either success or failure, and the parameters of the
system calls; for records generated by self-auditing processes, the body consists of the time audwrite(2) writes the records and the high-
level description of the event (see audwrite(2)).
The records in the audit trail are compressed to save file space. When a process is audited the first time, a pid identification record
(PIR) is written into the audit trail containing information that remains constant throughout the lifetime of the process. This includes
the parent's process ID, audit tag, real user ID, real group ID, effective user ID, effective group ID, group ID list, effective, permit-
ted, and retained privileges, compartment ID, and the terminal ID (tty). The PIR is entered only once per process per audit trail.
Information accumulated in an audit trail is analyzed and displayed by (see audisp(1M)).
