Copy a file to remote server with scp
This assumes that ssh runs on the remote machine.
To copy a file to a remote machine use the following command:
CODE:
-
scp /path/to/file user@remotehost:/path/to/destination
To set the access port use the -P switch:
CODE:
-
scp -P 1234 /path/to/file user@remotehost:/path/to/destination
If you need to copy from the remote host to the local host, reverse the above command
CODE:
-
scp user@remotehost:/path/to/file /path/to/destination
if you need to copy an entire directory full of files to a remote location, use the -r argument
CODE:
-
scp -r /path/to/directory/ user@remotehost:/path/to/destination/
If you are transferring logfiles or other highly compressible files, you might benefit from the -C argument. This turns on compression, which, while it will increase the CPU usage during the copy, should also increase the speed in which the file transfers.
Use the -l argument to limit how much bandwidth is used. Follow -l with the bandwidth you want to use in kilobits per second. So, to transfer a file and limit it to 256 Kbps use the following command
CODE:
-
scp -l 256 /path/to/file user@remotehost:/path/to/destination

Cakephp find(’list’) and select
How about a little trick to extend the find(’list’) functionality?..
Let’s say we need to display a list of users, but instead of just User.id and User.name we need to have User.id, as well as User.name and User.email combined. Unfortunately find(’list’) doesn’t have that type of functionality out-of-the-box. Well, that’s OK, we’ll make our own…
CODE:
-
function find($type, $options = array()) {
-
switch ($type) {
-
case 'superlist':
-
if(!isset($options['fields']) || count($options['fields']) <3) {
-
return parent::find('list', $options);
-
}
-
-
if(!isset($options['separator'])) {
-
$options['separator'] = ' ';
-
}
-
-
$options['recursive'] = -1;
-
$list = parent::find('all', $options);
-
-
for($i = 1; $i <= 2; $i++) {
-
$field[$i] = str_replace($this->alias.'.', '', $options['fields'][$i]);
-
}
-
-
return Set::combine($list, '{n}.'.$this->alias.'.'.$this->primaryKey,
-
array('%s'.$options['separator'].'%s',
-
'{n}.'.$this->alias.'.'.$field[1],
-
'{n}.'.$this->alias.'.'.$field[2]));
-
break;
-
-
default:
-
return parent::find($type, $options);
-
break;
-
}
-
}
Now all we have to do in our controller is:
CODE:
-
$this->User->find('superlist', array('fields'=>array('User.id','User.name','User.email'),'separator'=>' * '));
