What is execute permission?

Execute permission allows users to perform the following actions on a file or directory:

1. For Files:

   • Users with execute permission can run the file as a program or script. This means they can execute the file if it is a script (like a shell script) or a binary executable. Without execute permission, users cannot run the file, even if they have read permission to view its contents.

2. For Directories:

   • Users with execute permission on a directory can access and traverse the directory. This means they can enter the directory and access files and subdirectories within it, provided they have the necessary permissions for those files and subdirectories. However, having execute permission alone does not allow users to list the contents of the directory; they need read permission for that.

In summary, execute permission is essential for running executable files and for accessing directories.
