One of the great things about most system utilities is their portability. Many simply are distributed directly as an exe or in a zip file and are ready to use with no install required. Because of the simplicity of use, these types of applications are easily updated, however many lack any form of auto-update capability. Our UpdateFromWeb script solves this problem as it makes installing updates to portable applications, or any file available via the web for that matter, an automated process.
Usage. (if you find this helpful than please like our facebook page or follow us inventiongalaxy)
The UpdateFromWeb script usage is pretty simple and we have provided several examples below. You simply provide the source URL and the directory where the files to be updated on your computer are located and the script does the rest.
Features include:
Universal – works for any tools or files on any URL
Directory scanning for updating all applicable files in a local directory (including subdirectories)
Automatic unzipping and extraction
Direct URL downloads for single file updates
Case conversion for websites where URLs are case sensitive
New file detection for only updating newer versions
Automatic shutdown and restart of running applications which need to be updated
Can be run on demand or automated
There are more features included which are documented in the script file. Just open it in Notepad (or any other text editor) to view all the options.
The UpdateFromWeb script makes use of a couple of external tools which will need to be on your system prior to use. The download links for these tools are provided below and need to be placed in a folder in your system’s PATH variable (if in doubt, just put these required files in C:\Windows).
Not Just for Tools or Applications
As mentioned above, the UpdateFromWeb script can be used for any file which has a consistent URL. For example, if a project is updated nightly using the URL mysite.com/project.zip, you can use the UpdateFromWeb script to automatically download and extract the zip file to a local folder on your machine.
On a similar note, you can use the script to keep files and/or tools consistent across multiple machines. Just upload a file to a central location and an automated process running UpdateFromWeb can handle the rest.
Examples
The UpdateFromWeb script can be both used from the command line or hardcoded. Additionally, you can mix and match as needed.
Below are some examples which demonstrate the usage as well as the respective execution settings for both the command line and hardcode.
