-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.

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]+" \
