Your read command is backwards -
IFS sets the record separator for a read, by default it is space(s). This means the first text block gets put in a, second in b, third in the c variable.
You can also create arrays like that:
bash uses declare -a arrayname value1 value2 ... valuen
plus you can assign values directly to each element of an array.

Hi. I'm trying to write a script that reads a line on a file and runs a different command for a different line output.

pg_fetch_all
PG_FETCH_ALL(3)PG_FETCH_ALL(3)pg_fetch_all - Fetches all rows from a result as an arraySYNOPSIS
array pg_fetch_all (resource $result)
DESCRIPTION pg_fetch_all(3) returns an array that contains all rows (records) in the result resource.
Note
This function sets NULL fields to the PHP NULL value.
PARAMETERS
o $result
- PostgreSQL query result resource, returned by pg_query(3), pg_query_params(3) or pg_execute(3) (among others).
RETURN VALUES
An array with all rows in the result. Each row is an array of field values indexed by field name.
FALSE is returned if there are no rows in the result, or on any other error.
EXAMPLES
Example #1
PostgreSQL fetch all
<?php
$conn = pg_pconnect("dbname=publisher");
if (!$conn) {
echo "An error occurred.
";
exit;
}
$result = pg_query($conn, "SELECT * FROM authors");
if (!$result) {
echo "An error occurred.
";
exit;
}
$arr = pg_fetch_all($result);
print_r($arr);
?>
The above example will output something similar to:
Array
(
[0] => Array
(
[id] => 1
[name] => Fred
)
[1] => Array
(
[id] => 2
[name] => Bob
)
)
