Hello, I have a quick question that is not related to homework in any way shape or form (in case anyone wanted to know). My question is thus:
I have a file "temp" that has the two values say "5" and "3" (separated by a white space). Now, I want to simply write an if-else statement that reads file temp, and if $1 (5) is less than $2 (3) it prints OK, else NO. The values for $1 and $2 do change. My attempt is:
Code:
if [[ ($1 -lt $2) temp]];
then echo "OK"
else
echo "NO"
fi;
Right now I'm getting a syntax error. Help would be very much appreciated. Thanks in advance.

Hi,
Please don't berate me over the simplicity of these questions. I have recently gotten into bash shell scripting and enjoy it quite a bit.

In /etc/syslog.conf, if an error type is not specified, is it logged anywhere (most preferable is it logged to /var/log/messages) or not?

MAXDB_STMT_SQLSTATE(3) 1 MAXDB_STMT_SQLSTATE(3)maxdb_stmt_sqlstate - Returns SQLSTATE error from previous statement operationSYNOPSIS
string maxdb_stmt_sqlstate (resource $stmt)
DESCRIPTION
Returns a string containing the SQLSTATE error code for the most recently invoked prepared statement function that can succeed or fail.
The error code consists of five characters. '00000' means no error. The values are specified by ANSI SQL and ODBC.
Note
Note that not all MaxDB errors are yet mapped to SQLSTATE's. The value HY000 (general error) is used for unmapped errors.
RETURN VALUES
Returns a string containing the SQLSTATE error code for the last error. The error code consists of five characters. '00000' means no
error.
EXAMPLES
Example #1
Object oriented style
<?php
/* Open a connection */
$maxdb = new maxdb("localhost", "MONA", "RED", "DEMODB");
/* check connection */
if (maxdb_connect_errno()) {
printf("Connect failed: %s
", maxdb_connect_error());
exit();
}
$maxdb->query("CREATE TABLE temp.mycity LIKE hotel.city");
$maxdb->query("INSERT INTO temp.mycity SELECT * FROM hotel.city");
$query = "SELECT name, zip FROM temp.mycity ORDER BY name";
if ($stmt = $maxdb->prepare($query)) {
/* drop table */
$maxdb->query("DROP TABLE temp.mycity");
/* execute query */
$stmt->execute();
printf("Error: %s.
", $stmt->sqlstate);
/* close statement */
$stmt->close();
}
/* close connection */
$maxdb->close();
?>
Example #2
Procedural style
<?php
/* Open a connection */
$link = maxdb_connect("localhost", "MONA", "RED", "DEMODB");
/* check connection */
if (maxdb_connect_errno()) {
printf("Connect failed: %s
", maxdb_connect_error());
exit();
}
maxdb_query($link, "CREATE TABLE temp.mycity LIKE hotel.city");
maxdb_query($link, "INSERT INTO temp.mycity SELECT * FROM hotel.city");
$query = "SELECT name, zip FROM temp.mycity ORDER BY name";
if ($stmt = maxdb_prepare($link, $query)) {
/* drop table */
maxdb_query($link, "DROP TABLE temp.mycity");
/* execute query */
maxdb_stmt_execute($stmt);
printf("Error: %s.
", maxdb_stmt_sqlstate($stmt));
/* close statement */
maxdb_stmt_close($stmt);
}
/* close connection */
maxdb_close($link);
?>
The above example will output something similar to:
Warning: maxdb_stmt_execute(): -4004POS(23) Unknown table name:MYCITY [42000] <...>
Error: 42000.
