Hi.

To begin, this won't work:
Code:
lines=$(wc -l ./temp | cut -d" " -f1)

The reason is that -d takes every occurrence to be a field separator.

wc -l returns multiple leading spaces (separators).

A quick change would be:
Code:
lines=$(wc -l ./temp | awk '{print $1}')

edit: silly me, see below Smilie

MAXDB_PING(3)								 1							     MAXDB_PING(3)

maxdb_ping - Pings a server connection, or tries to reconnect if the connection has gone down

       Procedural style

SYNOPSIS
bool maxdb_ping (resource $link) DESCRIPTION
Object oriented style bool maxdb::ping (void ) Checks whether the connection to the server is working. If it has gone down, and global option maxdb.reconnect is enabled an automatic reconnection is attempted. This function can be used by clients that remain idle for a long while, to check whether the server has closed the connection and recon- nect if necessary. RETURN VALUES
Returns TRUE on success or FALSE on failure. EXAMPLES
Example #1 Object oriented style <?php $maxdb = new maxdb("localhost", "MONA", "RED", "DEMODB"); /* check connection */ if (maxdb_connect_errno()) { printf("Connect failed: %s ", maxdb_connect_error()); exit(); } /* check if server is alive */ if ($maxdb->ping()) { printf ("Our connection is ok! "); } else { printf ("Error: %s ", $maxdb->error); } /* close connection */ $maxdb->close(); ?> Example #2 Procedural style <?php $link = maxdb_connect("localhost", "MONA", "RED", "DEMODB"); /* check connection */ if (maxdb_connect_errno()) { printf("Connect failed: %s ", maxdb_connect_error()); exit(); } /* check if server is alive */ if (maxdb_ping($link)) { printf ("Our connection is ok! "); } else { printf ("Error: %s ", maxdb_error($link)); } /* close connection */ maxdb_close($link); ?> The above example will output something similar to: Our connection is ok!
