$N cycles a list of log files using the 'savelog' command. |
| 108 |
The list of files consists of all log files known to syslogd and additional |
| 109 |
files from list files you may specify. |
| 110 |
Without options called $N immediately begins doing its job. |
| 111 |
At last syslogd is restarted to make it use the emptied log files again. |
| 112 |
$N usually is called by CRON (or something like it). For this, |
| 113 |
place a link to it in one of the CRON directories. |

| 119 |
${b1}-l${b0}|${b1}--list${b0} |
| 120 |
$N only lists all known log files, then exits. |
