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
\fImyisam.log\fR
for
\fBmyisamlog\fR
and
\fIisam.log\fR
for
\fBisamlog\fR
if no
\fIlog_file\fR
argument is given. If tables are named on the command line, only those tables are updated.
