Can’t delete file on external hard drive – Mac

admin — Tue, 05 Jan 2010 02:04:29 +0000

I ran out of space on my external hard drive so I selected some folder file and pressed command-delete on my keyboard. They files looked as if though they were deleted but I notice the available space did not budge. I knew right than it was time to whip out the terminal to force the hard drive in to submission. 1) Type these command into Terminal window. MAKE SURE TO replace "disk" with the name of your external drive. If you have a problem creating a path to your external hard drive, type "cd" than a space and drag the icon of your hard drive to the terminal window. A path will be filled in automatically. Code: cd /Volumes/disk 2) Type out the remove command on then hidden trash directory. Code: sudo rm -rf .Trashes 3) It will ask you for your password. You will not see your password as you type for extra security. Once you are done, press enter. Code: Password: If you have a lot of files that needed deleting (ex: over 20GB) you may notice a dalyed response. If so, just keep an eye on the drive's avalible memory and you will notice a gradual increase of space right before your vary eyes.

PHP Remove last character from string

Want to remove the last character from your text. Just use Substr_Replace. This is how. PHP's substr_replace replaces text within a portion of a string. In this case we only want to replace the last character with nothing. Here is the code sample:

$old_string = "My-Category-";
// remove the last hyphen from the string
$new_string = substr_replace($old_string,"",-1);
echo $new_string;
// should now read "My-Category"

This should replace the last character of a string with nothing.

Here is a quick and easy way to remove underline-links in your html links. There are times when hyperlink-underlines can get in the way. One example is when there is an underscore "_" in your link address (usually an e-mail address), the underline can block the view of this underscore. This will lead some viewers to believe your address contains a space and not an underscore. Here is the code to fix this problem. For One Link: The code may look something like this: newflashmedia Typing in the blue code " style="text-decoration:none" ", will remove the hyperlink underline: style="text-decoration:none">newsourcemedia In order to affect other links repeat the process shown above.

Delete Warning

admin — Sat, 28 Feb 2004 00:22:11 +0000

Javascript that alert users when clicking on sensitive links (like delete or update links). You can customize the message with option to continue or cancel. Works great with PHP, ASP, and Perl administration sites. Introduction:

This javascript registers an event handler to a link on a page. When users click a link, the code executes a pop-up alert window asks them to confirm that this is the link they wanted to click. This is perfect for server side programs that delete files on a server or modify data in a database. (View the test page.)

Source Code:

Delete

Adding it to your site:

There are just a few areas you will need to change to customize the code for your use. Number one is the message inside of the javascript event handler ("Are you sure you want to delete \nrow number \"" name_cat "\"\nfrom the database"). Notice I used (\n) for a new line and (\") for quotes. You can delete them if you like. You can also delete or move around the (" name_cat ") inside the message. The second thing you will have to modify is the link values ('yourpage.php?delete=293','293'). Change the file name to your serverside program file path and change the id row numbers ('293') to the id row number of your database rows.
