I'm completing a join where I specify the outfile format....such as:
join -t \| -j1 1 -j2 1 -o 1.1 1.2 1.3 2.4 1.5 1.6 1.7 $OUTFILE TMP_INFILE > NEW_OUTFILE

DBA_HANDLERS(3) 1 DBA_HANDLERS(3)dba_handlers - List all the handlers availableSYNOPSIS
array dba_handlers ([bool $full_info = false])
DESCRIPTION dba_handlers(3) list all the handlers supported by this extension.
PARAMETERS
o $full_info
- Turns on/off full information display in the result.
RETURN VALUES
Returns an array of database handlers. If $full_info is set to TRUE, the array will be associative with the handlers names as keys, and
their version information as value. Otherwise, the result will be an indexed array of handlers names.
Note
When the internal cdb library is used you will see cdb and cdb_make.
EXAMPLES
Example #1
dba_handlers(3) Example
<?php
echo "Available DBA handlers:
";
foreach (dba_handlers(true) as $handler_name => $handler_version) {
// clean the versions
$handler_version = str_replace('$', '', $handler_version);
echo " - $handler_name: $handler_version
";
}
?>
The above example will output something similar to:
Available DBA handlers:
- cdb: 0.75, Revision: 1.3.2.3
- cdb_make: 0.75, Revision: 1.2.2.4
- db2: Sleepycat Software: Berkeley DB 2.7.7: (08/20/99)
