.SH "DESCRIPTION"
.PP
\fBmyisamlog\fR
processes the contents of a
MyISAM
log file\&. To create such a file, start the server with a
\fB\-\-log\-isam=\fR\fBlog_file\fR
option\&.
.PP
Invoke
\fBmyisamlog\fR
like this:
.sp
.if n \{\
.RS 4
.\}
.nf
myisamlog [\fIoptions\fR] [\fIfile_name\fR [\fItbl_name\fR] \&.\&.\&.]
.fi
.if n \{\
.RE
.\}
.PP
The default operation is update (\fB\-u\fR)\&. If a recovery is done (\fB\-r\fR), all writes and possibly updates and deletes are done and errors are only counted\&. The default log file name is
myisam\&.log
if no
\fIlog_file\fR
argument is given\&. If tables are named on the command line, only those tables are updated\&.
.PP
\fBmyisamlog\fR
