Bash-Script

It might sound strange at first but i must say that it's very useful specially if you have shell scripts as part of your application. Usually For making this scripts as automated as possible there should be a way to reuse the application's configurations (ips, passwords , etc) and not having to update a separate configuration file whenever anything changes in the application. It's not limited only to this and can be used to pass any kind of variables.

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.
