You are having an issue with the shutdown command. You wish to determine if the file is a script or an executable program. Which command would you use to determine this? 

Answer options:

A. od shutdown
B. file shutdown
C. test shutdown
D. cksum shutdown
E. attrib shutdown

B

The file command determines the file type file tests each argument in an attempt to classify it. There are three sets of tests, performed in this order: filesystem tests, magic tests, and language tests. The first test that succeeds causes the file type to be printed.
