NAME
auditreduce -- select records from audit trail files
SYNOPSIS
auditreduce [-A] [-a YYYYMMDD[HH[MM[SS]]]] [-b YYYYMMDD[HH[MM[SS]]]]
[-c flags] [-d YYYYMMDD] [-e euid] [-f egid] [-g rgid]
[-j id] [-m event] [-o object=value] [-r ruid] [-u auid] [-v]
[file ...]
DESCRIPTION
The auditreduce utility selects records from the audit trail files based
on the specified criteria. Matching audit records are printed to the
standard output in their raw binary form. If no file argument is speci-
fied, the standard input is used by default. Use the praudit(1) utility
to print the selected audit records in human-readable form.
The options are as follows:
-A Select all records.
-a YYYYMMDD[HH[MM[SS]]]
Select records that occurred after or on the given datetime.
-b YYYYMMDD[HH[MM[SS]]]
Select records that occurred before the given datetime.
-c flags
Select records matching the given audit classes specified as a
comma separated list of audit flags. See audit_control(5) for a
description of audit flags.
-d YYYYMMDD
Select records that occurred on a given date. This option cannot
be used with -a or -b.
-e euid
Select records with the given effective user ID or name.
-f egid
Select records with the given effective group ID or name.
-g rgid
Select records with the given real group ID or name.
-j id Select records having a subject token with matching ID.
-m event
Select records with the given event name or number. This option
can be used more then once to select records of multiple event
types. See audit_event(5) for a description of audit event names
and numbers.
-o object=value
file Select records containing path tokens, where the pathname
matches one of the comma delimited extended regular
expression contained in given specification. Regular
expressions which are prefixed with a tilde (`~') are
excluded from the search results. These extended regular
expressions are processed from left to right, and a path
will either be selected or deslected based on the first
match.
Since commas are used to delimit the regular expressions,
a backslash (`\') character should be used to escape the
comma if it is a part of the search pattern.
msgqid Select records containing the given message queue ID.
pid Select records containing the given process ID.
semid Select records containing the given semaphore ID.
shmid Select records containing the given shared memory ID.
-r ruid
Select records with the given real user ID or name.
-u auid
Select records with the given audit ID.
-v Invert sense of matching, to select records that do not match.
EXAMPLES
To select all records associated with effective user ID root from the
audit log /var/audit/20031016184719.20031017122634:
auditreduce -e root \
/var/audit/20031016184719.20031017122634
To select all setlogin(2) events from that log:
auditreduce -m AUE_SETLOGIN \
/var/audit/20031016184719.20031017122634
Output from the above command lines will typically be piped to a new
trail file, or via standard output to the praudit(1) command.
Select all records containing a path token where the pathname contains
/etc/master.passwd:
auditreduce -o file="/etc/master.passwd" \
/var/audit/20031016184719.20031017122634
Select all records containing path tokens, where the pathname is a TTY
device:
auditreduce -o file="/dev/tty[a-zA-Z][0-9]+" \
/var/audit/20031016184719.20031017122634
Select all records containing path tokens, where the pathname is a TTY
except for /dev/ttyp2:
auditreduce -o file="~/dev/ttyp2,/dev/tty[a-zA-Z][0-9]+" \
/var/audit/20031016184719.20031017122634
