HELP changing file permissions

does anyone know how to write a script that will change file permissions. because the Admin blocked me from altering any of my files im only allowed to read and i heard a script like this can bypass it but i dont know how to write it.


Display current users. Display user Ids only.

Display current process. Prompt the user to check all processes or a specific process. If the user selects all processes, display all process to the screen. If the user selects a specific user, display only those user processes.

Display a listing of the user’s directory and allow permission changes. Prompt the user to change filer permissions (y/n). If yes, prompt the user for the file name. Display the file’s permission. Ask the user to enter the add or remove the following permission: read the user, write user, execute user, read group, write group, execute group, read other, write other and execute other. After file permissions have been changed, display the file’s new permissions.

Display an alphabetized list of the users currently on the system.

This seems to me like a violation, sorry if I have not understood that properly. Why should an admin block access, any reason behind that?

This situation is kind of tricky, I will leave it to the mods/admins for the follow up.

Since read-access is available copy of the existing scripts should be possible to a temp location ( /tmp ) or atleast to user's home directory provided 'x' permission on directories that contain required files is not ceased by the admin.

In that case, a copy of the required file can be taken and still be edited as before.

What didn't work? - copying the required files to a temp folder

Does that mean 'x' permission on directory was ceased?

Why wouldn't your friends want to help you? There is more to this that you are telling. If you have violated some school policy on computer access then you have to deal with the consequences. A SysAdmin would not do this sort of stuff because you had a disagreement. If you feel this 'abuse' is unwarranted you should go to his manager or some school official and tell them that he is prohibiting you from doing your class assignments. You pay a tuition and part of that tuition goes to time allowed on the computer to do your assignments.
