.SH DESCRIPTION
|
|
.TP
|
|
.BR \-a | \-\-analyze
|
|
Analyze distribution of keys. Will make some joins in
|
|
MySQL faster.
|
|
.TP
|
|
.BR \-# | \-\-debug=...
|
|
Output debug log. Often this is 'd:t:o ,filename`
|
|
.TP
|
|
.BR \-\-character\-sets\-dir=...
|
|
Directory where character sets are
|
|
.TP
|
|
.BR \-C | \-\-default\-character\-set=...
|
|
Set the default character set
|
|
.TP
|
|
.BR \-d | \-\-description
|
|
Prints some information about table.
|
|
.TP
|
|
.BR \-e | \-\-extend\-check
|
|
Check the table VERY thoroughly. One need use this
|
|
only in extreme cases as isamchk should normally find
|
|
all errors even without this switch
|
|
.TP
|
|
.BR \-f | \-\-force
|
|
Overwrite old temporary files.
|
|
If one uses \-f when checking tables (running isamchk
|
|
without \-r), isamchk will automatically restart with
|
|
\-r on any wrong table.
|
|
.TP
|
|
.BR \-? | \-\-help
|
|
Display help and exit.
|
|
.TP
|
|
.BR \-i | \-\-information
|
|
Print statistics information about the table
|
|
.TP
|
|
.BR \-k | \-\-keys\-used=#
|
|
Used with '\-r'. Tell ISAM to update only the first
|
|
# keys. This can be used to get faster inserts!
|
|
.TP
|
|
.BR \-l | \-\-no\-symlinks
|
|
Do not follow symbolic links when repairing. Normally
|
|
isamchk repairs the table a symlink points at.
|
|
.TP
|
|
.BR \-q | \-\-quick
|
|
Used with \-r to get a faster repair. (The data file
|
|
isn't touched.) One can give a second '\-q' to force
|
|
isamchk to modify the original datafile.
|
|
.TP
|
|
.BR \-r | \-\-recover
|
|
Can fix almost anything except unique keys that aren't
|
|
unique.
|
|
.TP
|
|
.BR \-o | \-\-safe\-recover
|
|
Uses old recovery method; slower than '\-r' but can
|
|
handle a couple of cases that '\-r' cannot handle.
|
|
.TP
|
|
.BR \-O | " \-\-set\-variable var=option "
|
|
Change the value of a variable.
|
|
.TP
|
|
.BR \-s | \-\-silent
|
|
Only print errors. One can use two \-s to make isamchk
|
|
very silent
|
|
.TP
|
|
.BR \-S | \-\-sort\-index
|
|
Sort index blocks. This speeds up 'read\-next' in
|
|
applications
|
|
.TP
|
|
.BR \-R | \-\-sort\-records=#
|
|
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 time!)
|
|
.TP
|
|
.BR \-u | \-\-unpack
|
|
Unpack file packed with pack_isam.
|
|
.TP
|
|
.BR \-v | \-\-verbose
|
|
Print more information. This can be used with
|
|
\-d and \-e. Use many \-v for more verbosity!
|
|
.TP
|
|
.BR \-V | \-\-version
|
|
Print version and exit.
|
|
.TP
|
|
.BR \-w | \-\-wait
|
|
Wait if table is locked.
