       without options all tables on the command will be  checked
       for errors


       isamchk [OPTIONS] tables[.ISM]


       isamchk    [-a|--analyze]   [-#|--debug=...]    [--charac­
       ter-sets-dir=...]         [-C|--default-character-set=...]
       [-d|--description]     [-e|--extend-check]    [-f|--force]
       [-?|--help]     [-i|--information]      [-k|--keys-used=#]
       [-l|--no-symlinks]       [-q|--quick]       [-r|--recover]
       [-o|--safe-recover]     [-O|--set-variable     var=option]
       [-s|--silent]    [-S|--sort-index]   [-R|--sort-records=#]
       [-u|--unpack] [-v|--verbose] [-V|--version] [-w|--wait]


              Analyze distribution of keys. Will make some  joins
              in MySQL faster.

              Output debug log. Often this is 'd:t:o ,filename`

              Directory where character sets are

              Set the default character set

              Prints some information about table.

              Check the table VERY thoroughly.  One need use this
              only in extreme cases as  isamchk  should  normally
              find all errors even without this switch

              Overwrite old temporary files.  If one uses -f when
              checking tables (running isamchk without -r), isam­
              chk will automatically restart with -r on any wrong

              Display help and exit.

              Print statistics information about the table

              Used with '-r'. Tell ISAM to update only the  first
              aren't unique.

              Uses old recovery method; slower than '-r' but  can
              handle a couple of cases that '-r' cannot handle.

       -O| --set-variable var=option
              Change the value of a variable.

              Only  print  errors.   One  can  use two -s to make
              isamchk very silent

              Sort index blocks.  This speeds up  'read-next'  in

              Sort  records  according  to  an index.  This makes
              your data much more  localized  and  may  speed  up
              things  (It may be VERY slow to do a sort the first

              Unpack file packed with pack_isam.

              Print more information. This can be  used  with  -d
              and -e. Use many -v for more verbosity!

              Print version and exit.

              Wait if table is locked.
