How to find Linux bash script path (Self Path)

Blog
Linux
Sys Administration

Writing smart programs using bash script is not easy, there are many issues along the way and one of them is what i'm going to describe here.

Sometimes it's require for bash scripts to know their location, for example when they are part of a package and there are other require files (on the same location) for them to run properly, and it's also not possible to change the path to where they're located simply because they also need the current directory.

My site's comment system has integrated with social networks

Blog

I've integrated my website's comment system with social networks like facebook, twitter , etc.

Doing so has several advantages for both me and the visitors :

  • Keeping track of the sent comments
  • Having them on your favorite social network service
  • Sharing content and comments right inside the social network site
  • Not having to enter captcha , name , email ,etc because comments will be attached to your account on other sites.

Drupal's Acquia Marina Theme patched version!

Blog
Drupal

In Drupal it's possible to overwrite and extend a theme using sub-themes! So i usually create a custom theme for my site as a sub-Theme of a base theme and try to put all the site specific stuff to that theme instead of the base theme, although it's tricky! and sometimes i have to spend hours finding a workaround for not completely implemented sub themming features but i think it worth it.

PHP's forward compatible version compare

Blog
PHP
Programming

Sometimes the code is forward compatible, for example when it's compatible with all future PHP5 releases, put PHP's version_compare function does not support this (Perhaps because they know that they always break compatibility with every minor release!!!). This function supports .x, for the above example it's : 5.x

PHP's file system manipulation functions are not as complete as they should be specially when it comes to manging recursive folders. For addressing part of this issue i decided to write a smart function which can handle recursive file/folder copy easily.

As you may have noticed there are feature that i didn't have time to implement , so if you have time to extend this function please notify me as well :). It's also shared here
