$e "${b1}Function${b0}: |
107 |
$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. |
114 |
${b1}Usage${b0}: |
115 |
$b1$N [<Option>]$b0 |
116 |
${b1}Options${b0}: |
117 |
${b1}-t${b0}|${b1}--test${b0} |
118 |
Test mode. $N only prints out what would be done. |
119 |
${b1}-l${b0}|${b1}--list${b0} |
120 |
$N only lists all known log files, then exits. |
121 |
${b1}-h${b0}|${b1}--help${b0} |
122 |
Outputs this command line help and exits. |
123 |
${b1}-v${b0}|${b1}--version${b0} |

Shows title and version and exits." |
