benkulbertis / vm-backup.bat

Last active January 26, 2021 20:30

This backs up my Ubuntu VM on my Windows work machine. It works with any Virtualbox VM by passing the VM name as an argument. I hate batch.

	@echo off

	:: This is the name (in Virtualbox) of the VM you want to back up. Pass it as an argument or change the '%1' below to the VM name.
	set vmname=%1
	set bakroot=D:\VM Backups

	:: Get current date - from http://stackoverflow.com/a/203116
	for /f "tokens=2-4 delims=/ " %%a in ('date /t') do (set mydate=%%a-%%b-%%c)

	set /p start=The %vmname% VM is about to be backed up. Do you wish to continue (Y/[N])?

benkulbertis / pshutdown.sh

Last active December 26, 2015 17:29

This is a little bash script that will shut down the system when a process id exits. Just pass the relevant process id as an argument. It requires root/sudo to shutdown the system. The program Cuttlefish used to be able to do this but is now unmaintained. The kde program kshutdown can do this but requires a lot of dependencies on non-kde systems…

	#!/bin/bash

	# Usage: ./pshutdown.sh 1234
	# Or: ./pshutdown.sh $(pidof -s someprocess)

	pid=$1

	if [ -z "$pid" ]
	then
	echo "This script shuts down the system when a certain process exits. Please pass a process id as an argument to shut the system down when it exits." 1>&2

benkulbertis / duplicate_fixer()

Created January 24, 2011 02:34

Checks if the file name exists, if it does uses recursion to append the file name with a number that has not yet been used.

	function duplicate_fixer($fname, $count = 0, $old_fname = null){
	if($count != 0){
	$boom = explode(".", $old_fname);
	$boom[count($boom)-2] = $boom[count($boom)-2].$count.".";
	$fname = implode($boom);
	}
	if(file_exists($fname)){
	if($count == 0) $old_fname = $fname;
	$count++;
	$fname = duplicate_fixer($fname, $count, $old_fname);

benkulbertis / Image Upload Validation

Created January 11, 2011 22:13

Simple validation function to confirm that an image is actually an image, not a malicious .gif or .php file.

	function validate($upload){ // Must be a $_FILES array
	if($upload['size'] == 0) return "Image not uploaded correctly.";
	if($upload['size'] > 2097152){ // Measured in bytes, this is equal to 2MB
	$filesize = $upload['size']/1048576; // Converts from bytes to Megabytes
	return "The image you uploaded has a filesize that is too large. Please reduce your image to < 2MB. It is currently ".$filesize."MB.";
	}
	if(($upload['type'] != "image/gif" \|\| "image/jpeg" \|\| "image/png") \|\| ($this->imageinfo['mime'] != "image/gif" \|\| "image/jpeg" \|\| "image/png"))
	return "Uploads of that file type are not allowed. You need a jpg, png, or gif image.";
	$blacklist = array(".php", ".phtml", ".php3", ".php4", ".ph3", ".ph4");
	foreach ($blacklist as $item) {
