OK. If i am not mistaken Ubuntu uses dash as the default shell, which is (more or less, to be honest i don't know exactly) the same as bash. Perhaps there are some differences, but they are minor.

I understood that already. Now, such a task breaks down to two parts: first, write a script which takes a certain directory name and then executes the task you described below for that one directory (respectively the files in this directory). The second part is to create a list of these directories and then call the script with each of these directory names as arguments.

You probably have overseen my mentioning of the find-command. It has everything you need to do this second part (creating a list of directory names) and i suggest you follow the link i gave you and find out how it works. Once you get that covered we will find out how to write a script which does what you want for one directory supplied on the commandline.

No, it doesn't matter at all where the script resides. It is a good habit to put all your (personal) scripts into one directory - the common name being "bin" and located in your home directory. If there is no such directory i suggest you create it and then modify the file .profile in you home directory to include this line:

Code:

PATH="${PATH}:${HOME}/bin" ; export PATH

Now you can put all your scripts into this directory and call them without having to explicitly type the path. (You need to log off and log on again for this to take effect).

I hope this helps.
