Hello -
QUESTION:
Is there a way to override the default record length limitation over awk in Unix?
Or, is there a better way to do what I am trying to do than the way I am trying to do it now? (See BACKGROUND and CURRENT PROCEDURE below...)

Hi Friends,
Need some help in AWK.
Working on AIX 5
Have been trying the following functionality to make the record length fixed:
if( length(record) < 300 )
{
printf("%-300s\n", record);
}
In my opinion it will apply some fillers in the end.
Its is not making any... (4 Replies)
Hi Guys,
I wanted to print the length of each record and the record itself.
I tried the following awk ...
awk 'a=length(); {print $a,$0}' file1
But it is giving me the records instead of length.
and also, it giving me each record twice. Means the value of a is not the length of the... (0 Replies)

myisam_ftdump
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. Before using myisam_ftdump, be sure to issue a FLUSH TABLES statement first if the server is
running.
myisam_ftdump scans and dumps the entire index, which is not particularly fast. On the other hand, the distribution of words changes
infrequently, so it need not be run often.
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
You can use myisam_ftdump to generate a list of index entries in order of frequency of occurrence like this:
shell> myisam_ftdump -c mytexttable 1 | sort -r
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.
