In this example, login/logout messages for a particular day are summarized in a file. The target file is written in a directory other than the normal audit root.
# auditreduce -c lo -d 870413 -O /usr/audit_summary/logins |
The -O option creates an audit file with 14-character timestamps for both start-time and end-time, and the suffix logins:
/usr/audit_summary/19870413000000.19870413235959.logins |
