Is there any tool in which I can place the script and it can tell me the meaning of the whole script?
Yes, there is: it is called "scripting learning device", or, by its old name, "book". I suggest you get one and start reading.
Make sure that you are learning the right shell, though. In the first line of the script there should be a "shebang" identifying the shell to use, for example:
Code:
#! /usr/bin/bash
<...rest of the script....>
Widespread alternatives to this would be "ksh" (Korn Shell) or "sh" (either Bourne shell or the systems default shell, whatever that may be).
Most of the syntax is the same in these shells (they are all derived from the Bourne shell) but in some details they are different.
