You can open any read-only file in Unix assuming that you have the read permission. Any utility or program that can get access to that file in read mode can open it, which would include programs such as 'more', 'less', 'vi', 'cat', etc.
Read-only merely means you can't change it; but you could copy it or look at it.
There are no actual "hidden" files in Unix. The only way to hide the existence of a file is to place it in a folder that no one has read permissions for.
In UNIX: use function chmod

The .profile file is used to put any settings or changes to the login shell environment when you log in. This file is only read once during login.
All major operating systems allow developers to write code that can open a file in a variety of different ways, including "r" or "ro" (read-only) "rw" (read-write), "w" (write-only), and "a" (append, like "w" but starts at the end of the file, preserving the previous contents). In these operating systems, applications may choose to open a file as "read-only", which prevents accidental modification of the file by logic errors in the code.
I can't find any official reference to a 'pz' file - are you referring to a compressed PNG?
1. You (human) want to read an include file: use a text editor. 2. Your program wants to read a file: use open/fopen.
It depends on where the 000 is being used. For permissions, it would indicate that the file or directory or device has no permissions at all. For the 'umask' it would indicate that all newly created files or directories would have wide open permissions (world read, world write, etc.).
You will have to be more specific about what you intend to do. In general, a shell script by itself does not read file information and then do something with it. There may be calls to other scripting languages such as awk, perl, python, etc., that will actually read the information and process the data.
Read, write, execute, and functions in software objects.
Open it (open of fopen), read the data (read or fread), then close it (close or fclose).
To change a read only file into a read write file, first find the file to be edited. Then right click the file and click on properties. Next, click the general tab and clear the read only check box. Lastly, click on the OK button.
