Using bash, I'm trying to read a .properties file (name=value pairs), assigning an indirect variable reference for each line in the file.
The trick is that a property's value string may contain the name of a property that occurred earlier in the file, and I want the name of the 1st property to... (5 Replies)
The construct ${#parameter} returns the number of characters in the parameter and ${!parameter} specifies an indirect variable. My question is: How do I combine these two. What I want is ${#!parameter} but this gives an error.
Of course I can use:
dummy=${!parameter}

Hello,
is there a kind soul who can answer me, does the SH support double substitution known as indirect expansion similar to BASH? The syntax for bash is ${!var}.
For instance in bash I can write something like this:
VAR="value"
REF_VAR="VAR"
echo ${!REF_VAR}
and get the "value"... (1 Reply)

1 1
2 1
3 1
4 2
5 4
6 1
7 5

Think of column 1 as the referee and column 2 as the referrer.
Is there a good way to backtrack who referred who? I would like an output, for this example here to be:

dbx_fetch_row
DBX_FETCH_ROW(3) 1 DBX_FETCH_ROW(3)dbx_fetch_row - Fetches rows from a query-result that had the DBX_RESULT_UNBUFFEREDflag setSYNOPSIS
mixed dbx_fetch_row (object $result_identifier)
DESCRIPTION dbx_fetch_row(3) fetches rows from a result identifier that had the DBX_RESULT_UNBUFFERED flag set.
When the DBX_RESULT_UNBUFFERED is not set in the query, dbx_fetch_row(3) will fail as all rows have already been fetched into the results
data property.
As a side effect, the rows property of the query-result object is incremented for each successful call to dbx_fetch_row(3).
PARAMETERS
o $result_identifier
- A result set returned by dbx_query(3).
RETURN VALUES
Returns an object on success that contains the same information as any row would have in the dbx_query(3) result data property, including
columns accessible by index or fieldname when the flags for dbx_query(3) were set that way.
Upon failure, returns 0 (e.g. when no more rows are available).
EXAMPLES
Example #1
How to handle the returned value
<?php
$result = dbx_query($link, 'SELECT id, parentid, description FROM table', DBX_RESULT_UNBUFFERED);
echo "<table>
";
while ($row = dbx_fetch_row($result)) {
echo "<tr>
";
foreach ($row as $field) {
echo "<td>$field</td>";
}
echo "</tr>
";
}
echo "</table>
";
?>
