Linux Shell Bridge (Passing variables from scripting langauges like PHP to Linux Shell)

admin — Thu, 18 Feb 2010 19:21:09 +0000

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.

How to find Linux bash script path (Self Path)

admin — Mon, 04 Jan 2010 03:30:47 +0000

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.

This is one of the issues i had for several months, i couldn't find any specific information about it and never had time to trace it in order to find a solution. But today i managed to fix it by reading many threads and articles and then tracing it from the beginning , since i'm not the only one with this problem i decided to share it.

I used CentOS 5.3 for this tutorial , but it might be still useful even if you're using a Debian based distribution.

CentOS/RHEL5 does not detect some onboard network cards +Videos

admin — Fri, 09 Oct 2009 18:08:08 +0000

CentOS's kernel is a very old kernel comparing to many other distributions. The reason is stability but some times it gets annoying.

For example today i wanted to upgrade CentOS 5.2 server at work to 5.3. to make this process as trouble free as possible i cloned the server into another computer but once it booted , i noticed that it doesn't detect new computer's on board network card! and it was impossible to do the upgrade without Internet.

How to dump all MySQL databases into indivisual files at once

admin — Mon, 14 Sep 2009 16:26:19 +0000

It dumps all the databases but each database into a different file :
