What is the numerical value for the r-xr--r-- permission?644544411522I don't know

To decode the permission value 644544411522, we need to understand the representation of file permissions in UNIX-like systems. File permissions are typically represented as a three-digit octal number.

1. Break Down the Problem
   Analyze the permission representation:

   • The first digit represents the owner's permissions.
   • The second digit represents the group's permissions.
   • The third digit represents other users' permissions.

2. Relevant Concepts
   Permissions are expressed in octal format where:

   • Read (r) is represented by 4.
   • Write (w) is represented by 2.
   • Execute (x) is represented by 1.

   Each permission is summed to create a digit, which results in a number from 0 to 7 for each category.

3. Analysis and Detail
   The given permission value of 644544411522 seems incorrect in length for standard UNIX permissions. Let's analyze 644 as it’s the typical representation:

   • Owner: 6 (Read + Write = 4 + 2)
   • Group: 4 (Read = 4)
   • Others: 4 (Read = 4)

   To confirm this:

   • Owner permissions: rw-
   • Group permissions: r--
   • Others permissions: r--

4. Verify and Summarize
   Based on the analysis, 644 in numbers means:

   • Owner has read and write permissions.
   • Group has read permission.
   • Others have read permission.

   The 544411522 portion likely contains additional numbers that don't correspond to standard file permission notations.

Final Answer

The numerical value representing the permission 644 corresponds to:

• Owner: rw- (6)
• Group: r-- (4)
• Others: r-- (4)
