Automating Linux Script

I want to automate the creation or processing of the following:

  • Directory and subdirectory creation for your scenario company
  • Files in each of the directories
  • Symbolic links from 2 subdirectories to their parent directories
  • Setting appropriate file permissions for the directories and files:
    [list]
  • Directories
    [list]
  • the file owner can read, modify and access the scenario company directories,
  • the group members can read and access the scenario company directories,
  • everyone else has no access.
    [/list]
  • Files
    [list]
  • The owner can read and modify the file,
  • the group members can only read the file
  • everyone else has no permissions at all.
    [/list]

    [/list]
  • Include branching to only execute the directory, file and link commands only if the directory or file does not already exist.
  • Set up an error log file with commands to route the errors messages into it.

However, I have only been using Linux for a few weeks now and this is proving to be extremely complicated. I have read tutorials on automating but cannot understand it. This is a school assignment due today by 11:59pm central time. Ant assistance would be greatly appreciated!
