2 questions:
1.A shell script has owner, group, and others (world) execute permissions
set but only read permissions set for group and others. Can this script
be executed by the owner, why / whynot?
2.Explain what the following does? What is the working directory after
the command executes? DO NOT RUN THE COMMAND.

cd /; tar cf - etc | ( cd /tmp; tar -xf - )

1. you mean 155 for the file ?

The owner cannot execute this as it has to read the file for execution, but 'read' is not permitted on the file, although execute is.

2. I did not even try this.
