I'm trying to figure out what some of your code is trying to do. Can you please answer the following questions:

1. Will the user running this script have read access to files matching the pattern /home/user/myfiles/*/*/*.log.*? If yes, why are you wasting time making copies of these files? If not, why are you copying these files into a directory and changing their access permissions such that every user with access to your system will be able to read this (presumably private) data?

2. Why does anyone need write or execute permission to the log files you are copying while this script is running?

3. What exactly are you trying to do with the command?:
Code:
chmod 775 files =/tmp/log/*.*

What it does do is change the permissions of a file named files and of all files in the directory located in the current working directory named =/tmp/log whose names in that directory contain the string .log. so that any process running with the user ID of the file's owner or with a group ID matching the file's group will have read, write, and execute permissions and all other processes will be able to read and execute them.
