AUDITREDUCE(1)            BSD General Commands Manual           AUDITREDUCE(1)

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 argu-ment argument
     ment is specified, 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/2__31_16184719.2__31_17122634:

           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
