myisam_ftdump(1) MySQL Database System myisam_ftdump(1)
NAME
myisam_ftdump - display full-text index information
SYNOPSIS
myisam_ftdump [options] tbl_name index_num
DESCRIPTION
myisam_ftdump displays information about FULLTEXT indexes in MyISAM
tables. It reads the MyISAM index file directly, so it must be run on
the server host where the table is located
Invoke myisam_ftdump like this:
shell> myisam_ftdump [options] tbl_name index_num
The tbl_name argument should be the name of a MyISAM table. You can
also specify a table by naming its index file (the file with the .MYI
suffix). If you do not invoke myisam_ftdump in the directory where the
table files are located, the table or index file name must be preceded
by the path name to the table's database directory. Index numbers begin
with 0.
Example: Suppose that the test database contains a table named
mytexttablel that has the following definition:
CREATE TABLE mytexttable
(
id INT NOT NULL,
txt TEXT NOT NULL,
PRIMARY KEY (id),
FULLTEXT (txt)
);
The index on id is index 0 and the FULLTEXT index on txt is index 1. If
your working directory is the test database directory, invoke
myisam_ftdump as follows:
shell> myisam_ftdump mytexttable 1
If the path name to the test database directory is
/usr/local/mysql/data/test, you can also specify the table name
argument using that path name. This is useful if you do not invoke
myisam_ftdump in the database directory:
shell> myisam_ftdump /usr/local/mysql/data/test/mytexttable 1
myisam_ftdump supports the following options:
o --help, -h -?
Display a help message and exit.
o --count, -c
Calculate per-word statistics (counts and global weights).
o --dump, -d
Dump the index, including data offsets and word weights.
o --length, -l
Report the length distribution.
o --stats, -s
Report global index statistics. This is the default operation if no
other operation is specified.
o --verbose, -v
Verbose mode. Print more output about what the program does.
