The tabdump command displays the header and all the rows of the specified table in CSV (comma separated values) format.

tables will be displayed.

=head1 OPTIONS

=over 10

=item B<-?|-h|--help>

Display usage message.

=item B<-d>

Show descriptions of the tables, instead of the contents of the tables.  If a table name is also specified, descriptions of the columns (attributes) of the table will be displayed.  Otherwise, a summary of each table will be displayed.

=item B<-n>

Shows the most recent number of entries as supplied on the -n flag from the auditlog or eventlog table.  

=item B<-f>

File name or path to file in which to dump the table. Without this the table is dumped
to stdout.  Using the -f flag allows the table to be dumped one record at a time. If tables are very large, dumping to stdout can cause problems such as running out of memory. 

=item B<-w> I<'attr==val'> B<-w> I<'attr=~val'> ...

Use one or multiple -w flags to specify the selection string that can be used to select particular rows of the table. See examples.

Operator descriptions:

        ==        Select nodes where the attribute value is exactly this value.
        !=        Select nodes where the attribute value is not this specific value.
        >         Select nodes where the attribute value is greater than this  specific value.
        >=        Select nodes where the attribute value is greater than or equal to this  specific value.
        <         Select nodes where the attribute value is less than this  specific value.
        <=        Select nodes where the attribute value is less than or equal to this  specific value.
        =~        Select nodes where the attribute value matches the SQL LIKE value.
        !~        Select nodes where the attribute value matches the SQL NOT LIKE value.

=item *

To display the contents of the site table:

B<tabdump> B<site>

To display the contents of the nodelist table where the groups attribute is compute :

B<tabdump>  B<-w 'groups==compute'> B<nodelist>

=item *

To display the contents of the nodelist table where the groups attribute is comput% where % is a wildcard and can represent any string  and the status attribute is booted :

B<tabdump>  B<-w 'groups=~comput%'> B<-w 'status==booted'> B<nodelist>

=item *

To display the records of the auditlog on date  2011-04-18 11:30:00 :

B<tabdump>   B<-w 'audittime==2011-04-18 11:30:00'> B<auditlog>

=item *

To display the records of the auditlog starting on 2011-04-18:

tabdump -w 'audittime>2011-04-18 11:30:00' auditlog

=item *

To display the 10 most recent entries in the auditlog:

tabdump -n 10 auditlog

=item *

To see what tables exist in the xCAT database:

B<tabdump>

=item *

To back up all the xCAT database tables, instead of running B<tabdump> multiple times, you can use the B<dumpxCATdb> command as follows:

B<dumpxCATdb -p /tmp/xcatbak >

See the B<dumpxCATdb> man page for details.

=item *

To display a summary description of each table:

B<tabdump> B<-d>
